Add tag input to release-build workflow_dispatch (#5020)

## Summary
- Adds an optional `tag` input to the `workflow_dispatch` trigger of `release-build.yml`.
- Both `cli` and `wheel` jobs now check out the given tag when provided.
- GoReleaser omits `--snapshot` when a tag is dispatched, producing
versioned binaries for that tag.
