The bot does not update snapshots in examples

[krassowski]

The bot does not update playwright snapshots used in examples; this adds to the workload when making changes with visual impact on the interface.

For example this had an impact on PRs #16142 and #15948.

We should consider adding a new job in the workflow triggered on comment asking the bot to update snapshots:

jupyterlab/.github/workflows/galata-update.yml

Lines 11 to 12 in 2ceabd8

	jobs:
	update-galata-snapshots:

Information for the interested contributor, this is gonna be tricky because example tests are not regular Playwright tests. They imply the creation of a dummy package in which we copy the test file and the reference snapshots, execute the test and finally copy back the test results:

jupyterlab/examples/example_check.py

Line 65 in 9b75722

async def run_browser(url):

example tests are not regular Playwright tests

Could they be converted to regular Playwright tests, if that can ease maintenance and align with the rest of the code base?

Probably, the main technical difficulty is that the current script is dealing with the server application being specific for each example.
