Feature: Improve structure of Event schedule.

[tovmasharrison]

Currently, the structure of the event schedule in the events.json and wmt_events.json files is not optimal for readability and clarity, especially when dealing with sessions containing multiple events within the overall schedule. (For example: WMT23)

To improve the structure and readability of the event schedule, we can modify the structure within the JSON files as follows:

• Current Structure:

"multiday_schedule": [
      [
        {
          "start_time": "8:45",
          "title": "Opening Remarks"
        },
        {
          "start_time": "9:00",
          "title": "Session 1: Shared Task Overview Papers I"
        },
        {
          "start_time": "9:00",
          "title": "<a href=\"https://aclanthology.org/2023.wmt-1.1.pdf\">Findings of the 2023 Conference on Machine Translation (WMT23): LLMs Are Here but Not Quite There Yet</a> <br>Tom Kocmi, Eleftherios Avramidis, Rachel Bawden, Ondřej Bojar, Anton Dvorkovich, Christian Federmann, Mark Fishel, Markus Freitag, Thamme Gowda, Roman Grundkiewicz, Barry Haddow, Philipp Koehn, Benjamin Marie, Christof Monz, Makoto Morishita, Kenton Murray, Makoto Nagata, Toshiaki Nakazawa, Martin Popel, Maja Popović, Mariya Shmatova"
        },
        {
          "start_time": "9:30",
          "title": "<a href=\"https://aclanthology.org/2023.wmt-1.2.pdf\">Findings of the WMT 2023 Biomedical Translation Shared Task: Evaluation of ChatGPT 3.5 as a Comparison System</a> <br>Mariana Neves, Antonio Jimeno Yepes, Aurélie Névéol, Rachel Bawden, Giorgio Maria Di Nunzio, Roland Roller, Philippe Thomas, Federica Vezzani, Maika Vicente Navarro, Lana Yeganova, Dina Wiemann, Cristian Grozea"
        },
        {
          "start_time": "9:45",
          "title": "<a href=\"https://aclanthology.org/2023.wmt-1.3.pdf\">Findings of the WMT 2023 Shared Task on Discourse-Level Literary Translation: A Fresh Orb in the Cosmos of LLMs</a> <br>Longyue Wang, Zhaopeng Tu, Yan Gu, Siyou Liu, Dian Yu, Qingsong Ma, Chenyang Lyu, Liting Zhou, Chao-Hong Liu, Yufeng Ma, Weiyu Chen, Yvette Graham, Bonnie Webber, Philipp Koehn, Andy Way, Yulin Yuan, Shuming Shi"
        },
        {
          "start_time": "10:00",
          "title": "<a href=\"https://aclanthology.org/2023.wmt-1.4.pdf\">Findings of the Second WMT Shared Task on Sign Language Translation (WMT-SLT23)</a> <br>Mathias Müller, Malihe Alikhani, Eleftherios Avramidis, Richard Bowden, Annelies Braffort, Necati Cihan Camgöz, Sarah Ebling, Cristina España-Bonet, Anne Göhring, Roman Grundkiewicz, Mert Inan, Zifan Jiang, Oscar Koller, Amit Moryossef, Annette Rios, Dimitar Shterionov, Sandra Sidler-Miserez, Katja Tissi, Davy Van Landuyt"
        },
        {
          "start_time": "10:15",
          "title": "<a href=\"https://aclanthology.org/2023.wmt-1.5.pdf\">Findings of the WMT 2023 Shared Task on Parallel Data Curation</a> <br>Steve Sloto, Brian Thompson, Huda Khayrallah, Tobias Domhan, Thamme Gowda, Philipp Koehn"
        },
        {
          "start_time": "10:30",
          "title": "☕️"
        },
        {
          "start_time": "11:00",
          "title": "Session 2: Shared Task System Description Posters I <br>General Translation Task"
        }

"one_day_schedule": [
    ...
]

• Proposed Structure:

{
    "start_time": ...,
    "title": "....",
    "type": "Shared Task Overview Papers I",
    "speakers": ["Tom Kocmi", "Eleftherios Avramidis", ...., "Mariya Shmatova"],
    "url": "https://aclanthology.org/2023.wmt-1.1.pdf"
}

The URL needs to be linked accordingly inside the .html file so we don't link it with <a></a> tags in the .json files.

Implementation Steps:

What to update:

1. The structure of the event schedule in both events.json and wmt_events.json files.
2. The schemas accordingly (i.e. _events_schema.json, _wmt_events_schema.json)
3. The layouts to match the changes (i.e. _layouts/event.html, _layouts/wmt_events.html)
4. Change the old version of the schedule in each event to the new version.

Additional Notes:

The proposed structure is not strict to follow. However, it shows the main idea.
