ci: add golangci-lint for linting

[sukunrt]

Configures ci to use golang-ci for linting.

The workflow is copied from quic-go. The os specific checks don't add too much value, I guess. I am fine with keeping only linux.

I couldn't get the unparam linter to detect unused parameters in functions. I guess it is aggressive about not raising failse positives. Using revive for unparam check.

I fear errcheck may be too much some times. We can disable / configure that one when we come across a change that warrants it.

See: https://github.com/libp2p/go-libp2p/actions/runs/14307422981/job/40094362132?pr=3269
for a failure.

See: #1843 for past discussion on this.

Fixes: #3248

@galargh any reason golangci-lint isn't part of unified ci?

Other repos could also benefit from it

There's this discussion where not everyone's convinced they need this. ipld/ipld#92

The current plan is to add it as an optional additional step that could be easily enabled via Unified CI's config. Once it's out, I'll make sure to update the configuration here.
