Update how Codecov is invoked in pull requests

[dcshzj]

We have always been using Codecov Bash uploader to perform code coverage checks for our pull requests, and to annotate on the pull request files on the specific lines that are not covered by tests. However, this practice has been deprecated since 1 February 2022.

We should update the way we invoke Codecov as part of our pull request checks, particularly in 2 aspects:

1. Make use of new/updated ways to invoke Codecov
2. Make Codecov aware of Windows-specific code, so that code are not flagged unnecessarily when they are actually covered in our Windows-based tests

@dcshzj does this apply to AB3 too? https://github.com/se-edu/addressbook-level3

Seems like it, because AB3 is using codecov/codecov-action@v1 from what I see in the gradle.yml file, and based on their changelog, they will sunset that version at the same time as the bash uploader.

Thanks for checking @dcshzj . Is the deprecated one still working? If yes, when is it expected to stop working altogether?

I could not find any authoritative information about the exact deprecation timeline. There is one pending PR to update the deprecation warning but it has not yet been merged or looked into. I am guessing that we can expect it to stop working "very soon".
