update codecov process

[hirosassa]

Description

In this PR, I replaced codecov process to official github action.

Motivation and Context

codecov command is currently deprecated.
ref: https://docs.codecov.com/docs/about-the-codecov-bash-uploader

Have you tested this? If so, how?

Fixed CI worked.

Take a look at the Github Action results. Failures with the codecov changes.

@dlstadther Thanks for your comment! Could you please review this PR?

[dlstadther]

CI execution looks good and can confirm that codecov received the test coverage results. However, unrelated to your change (i think), it looks like CodeCov is complaining about the validity of the luigi conf yaml file. Though, the yaml indentation that codecov reports looks different than the luigi/codecov.yml.

The master build is now failing because codecov's upload is requiring a token for protected branches...

debug - 2025-01-19 01:49:47,309 -- Upload result --- {"result": "RequestResult(error=RequestError(code='HTTP Error 400', params={}, description='{\"message\":\"Token required because branch is protected\"}\\n'), warnings=[], status_code=400, text='{\"message\":\"Token required because branch is protected\"}\\n')"}
error - 2025-01-19 01:49:47,309 -- Upload failed: {"message":"Token required because branch is protected"}

Odd how the old cli execution was able to upload coverage, but this method can't.
@hirosassa , could you look into options without the token? (or to reference an existing token if one is mentioned by the tox configuration.

Otherwise, we may need to involve a Spotify employee who has admin rights to help.
