chore: Remove explicit caching in workflows (#34)

[alexandear]

Pull Request Template

Description

The PR removes explicit caching actions/caching in workflows because actions/setup-go@v4 has built-in caching. For more information, visit https://github.com/actions/setup-go#caching-dependency-files-and-build-outputs

The cache added in the commit 77584cf.

Additionally, the PR updates the versions of the actions: setup-go to v5 and checkout to v4. It also reorders them so that checkout comes before setup-go.

For consistency with pr.yaml and release.yaml, this PR introduces env.GOLANG_VERSION.
