Test with Pyodide 0.27.2

[agriyakhetarpal]

Description

This PR bumps the Pyodide runtime version in our CI from 0.27.0a2 to 0.27.2. Fixes a couple of failing tests.

[agriyakhetarpal]

I managed to fix one out of two failing tests, and the integration tests haven't proceeded to run (maybe they should be their separate job instead of a step).

I don't fully understand the failure with test_load_binary_wheel2 yet, but I can take a look at it in depth again later in the day.

Thanks!

The failing test should use the fixture selenium_standalone_micropip, not selenium. Otherwise the micropip in the Pyodide distribution will be used (which was 0.8.0 in 0.27.2 and 0.6.0 in 0.27.0a2). I think we should find all invalid fixtures and replace it.

I don't fully understand the failure with test_load_binary_wheel2 yet, but I can take a look at it in depth again later in the day.

Looks like we are appending file:/// when no scheme is given, but it does not update the scheme in the parsed_url, so micropip fails here saying the scheme is None.

Thanks for the pointer, @ryanking13! I fixed the tests, but I don't know if I did the change correctly.

Thanks! I left a comment about the scheme handling, otherwise looks good to me.

test_load_binary_wheel2 is failing consistently due to pickling errors, but I don't think it's related. I retried it a few times to see if it's not a flake, it isn't. Do you have any ideas, @hoodmane? I'll revert the change for the time being.

[agriyakhetarpal]

I guess it was related, indeed, tests are passing now. I don't immediately see from f1de916 as to why.

[agriyakhetarpal]

Thanks for the review! I've opened new issues so that we can track both items. I guess we should be fine to merge here, so I'll press the button.
