chore(go-lint): [NOJIRA-1234] comment fix command (#152)

Changes the comment if linting issues are found so that:
- `golangci-lint` fixes the issues found
- uses the `main` branch as a reference so that only changes are
inspected
- includes GitHub PAT and initialises git so that private packages can
be downloaded in the Docker container on demand
