feat: add CI / CD

[NMFR]

Add Github actions workflows that automatically:

• Run the linter, tests and build on every commit pushed to a PR or to the main branch.
• Build and push the ci container stage to this repository registry to cache the ci container (so it doesn't have to build on every Github action triggered).
• Create a new Github release on every tag matching the v*.*.* pattern.

Additionally upgrade the golangci-lint version and add the -buildvcs=false flag to avoid the error:

error obtaining VCS status: exit status 128

Caused by the git repository file ownership being different that the executing user.
