ci: use GI_TOKEN so we can run ci on other platforms

Summary:

Starting to have a play with forgejo, on this platform you cannot define
secrets that have a prefix of `GITHUB_`. I still want to maintain CI on github
for any pull requests that may come in.

The plan in to use the `GITHUB_TOKEN` when we are running on github and use the
`GH_TOKEN` when we are running on forgejo

Test Plan:

Run the CI on github and forgejo, this will need to be a manual process to
validate this works.
