fix: fetch experiment in case config data is not contained

[keita-determined]

Description

There is a bug after #8765
The context menu (right click menu) in the new experiment table has Hyperparameter Search option. When the option is clicked on the new experiment table view, the data from experiment-search API does not contain config data since it is deprecated in #8732 and unlinked on web in #8765. Therefore, we need to fetch experiment data through getExperiment API for the missing config.
Before this fix, Unexpected Error shows up after clicking context menu.

Test Plan

• Check if Hyperparapeter serach modal shows data and works as before by clicking context menu in the new experiment table, and Hyperparapeter Search button in experiment detail page

[ashtonG]

given that we use this modal in the details view (where we should have the full config available), could we instead show a loader modal in the context menu that then shows the hyperparameter search modal once the experiment is fetched?

sorry, to reword, perhaps instead have the context menus in the experiment lists show a modal that just consists of a loading spinner that loads the full experiment, then passes it on to the hyperparameter search modal.
