perf(tests): improved e2e test performance by up to 3x

[Sebastian-Webster]

Improved end-to-end test performance by up to 3x

Changes:

1. Upgraded puppeteer to latest (22.10.0 as of writing) and puppeteer-cluster to latest (0.24.0 as of writing). The benefits of this I found are:

• Version is supported by Puppeteer (the previously used version is now deprecated)
• Fixes stability issues in Ubuntu 22.04 and newer
• The downloaded version of Google Chrome on Apple Silicon Macs is now ARM-based, increasing performance and removing the need for the Rosetta translation layer

2. Concurrency limit for puppeteer-cluster is set to os.availableParallelism(), allowing computers with more CPU cores to take advantage of the available compute and putting less load on computers with less than 5 cores

3. When running tests, Puppeteer no longer waits a hard-coded amount of time (previously 2,200ms). It now waits in this order:

• Wait for page load
• Wait for network requests to finish
• Wait for all intervals in the page to be cleared
• Wait for all timeouts in the page to expire
• Wait for the chart animation to finish

4. Updated line/realtime test to only run the interval twice (it only ran twice before this PR, it ran every 1000ms in a 2,200ms window, but now that Puppeteer is waiting for intervals to be cleared, a limit needed to be set to prevent Puppeteer from timing out)

5. In the new version of Puppeteer, page.waitFor() is no longer a function. The page.waitFor() in tests/e2e/spec/utils.js has been replaced with a promisified timeout.

6. In the new version of Puppeteer, the filepath for the install Chrome file is now node_modules/puppeteer/install.mjs instead of node_modules/puppeteer/install.js. This filepath change has been made to the CONTRIBUTING.md file.

7. Changed puppeteer-cluster concurrency from CONCURRENCY_PAGE to CONCURRENCY_BROWSER to fix various issues with concurrency after the Puppeteer upgrade
