fix: add GOPRIVATE and RELENG_GITHUB_TOKEN for private module access

golangci-lint and go test fail when the caller repo depends on private
ConductorOne modules like baton-http. This adds:

- GOPRIVATE=github.com/conductorone/* to skip go proxy
- Optional RELENG_GITHUB_TOKEN secret for private repo access
- git config step only runs when token is provided

Fixes lint errors on baton-http based connectors (36 repos)
