feat: convert to an Analyzer

[ldez]

To ease the integration inside golangci-lint, I converted the Run function into an Analyzer.

@ldez thanks for the contribution. We appreciate the effort 🙏

Currently we are in a busy state, since the holidays are around the corner.

I will review this PR and ask a peer to double check it.

That said, this will likely happen next week.

Thanks for being patient.

Best regards and happy holidays (you too @martialblog).

Thanks for the contribution.

Do you intend to create a PR on golangci-lint, or are we expected to do so?

Kind regards

Thank you for merging the PR, I handle the update inside golangci-lint.
