Debug codecov issues

[gtdang]

Debugging GitHub actions for uploading codecov report. Unittest actions have been failing since switching to using the codecov-action v4 in #758 .

Codecov uploads have sporadically been failing due to rate-limiting of 'tokenless' uploads. It is not actually tokenless, see explanation below.

If Codecov detects that reports are being uploaded from a fork of an open source repository, Codecov will automatically switch to tokenless uploading...Token-less uploads still use a token to upload to Codecov - just that it's Codecov's Github token instead of the project's own. As such, uploading to Codecov via tokenless (whether it's via forks, or by an older version of the Codecov action) ends up consuming from the shared request pool of a lot of Codecov users, instead of your own. Therefore, there may be cases when uploading to Codecov via tokenless fails because Codecov is being rate limited. Source

One option is changing the setting fail_ci_if_error = false. This will not fail the test if the coverage isn't uploaded. There just won't be a coverage report.

Bash implementation doesn't fail the workflow. Seems to be an error during upload and it's requesting a token. I'm not sure if a new report was actually generated...

Bash uploader is being deprecated, though there has been no indication on when they are fully deprecating it.

Closing because this was just used to debug workflows.
