Added link to GitHub commit if prerelease version

refs https://ghost.slack.com/archives/C025584CA/p1678886661494989?thread_ts=1678886465.260379&cid=C025584CA

- if we're running a prerelease, our usual format is `<major>.<minor>.<patch>-pre.<commit hash>.<build>`
- if you wanna see what commit it was built on, you have to copy and
  paste the hash into a GitHub URL
- this provides an easier route to the commit by detecting if the
  version is our special format and links direct to GitHub if so
