Remove codecov

[mdelapenya]

Proposal

There a lot of PRs failing codecov's GH check even though the modified files are i.e. only docs

Examples:

• updating Ryuk version, fails codecov Update testcontainers/ryuk version to 0.3.4 #564
• adding colima docs, fails codecov docs: add docs regarding Colima usage #547
• adding contributing guides, fails codecov chore: add CONTRIBUTING file #539

We are not paying attention at the code coverage at this moment, so I recommend removing it until a) there is less or even zero noise in the PRs; and b)we look at the code coverage to identify not covered parts of the codebase.

Can I take this issue?

Is it enough to comment the job inside CI pipeline or you want completely remove it?

@misantron It should be removed, no need to leave it in commented out (it can always be looked up from Git history when necessary).
