GitHub's macOS runners for the past while have had some bad clock drift
which sometimes prevents this action from working with the error:
```console
'Issued at' claim ('iat') must be an Integer representing the time that the assertion was issued
```
`@octokit/auth-app` already has logic to handle this so we can defer to
that code.
Fixes https://github.com/actions/create-github-app-token/issues/55
Currently, `actions/create-github-app-token` always/unconditionally
revokes the installation access token in a `post` step, at the
completion of the current job. This prevents tokens from being used in
other jobs.
This PR makes this behavior configurable:
- When the `skip-token-revoke` input is not specified (i.e. by default),
the token is revoked in a `post` step (i.e. the current behavior).
- When the `skip-token-revoke` input is set to a truthy value (e.g.
`"true"`[^1]), the token is not revoked in a `post` step.
This PR adds a test for the `skip-token-revoke: "true"` case.
This is configurable in other app token actions, e.g.
[tibdex/github-app-token](https://github.com/tibdex/github-app-token/blob/3eb77c7243b85c65e84acfa93fdbac02fb6bd532/README.md?plain=1#L46-L47)
and
[wow-actions/use-app-token](https://github.com/wow-actions/use-app-token/blob/cd772994fc762f99cf291f308797341327a49b0c/README.md?plain=1#L132).
[^1]: Note that `"false"` is also truthy: `Boolean("false")` is `true`.
If we think that’ll potentially confuse folks, I can require
`skip-token-revoke` to be set explicitly to `"true"`.
Follow up to #36. I just wanted to do some refactoring but turns out I
missed to pass the custom `request` instance to `createAppAuth`. It will
fallback to the default `request` which does not respect
`GITHUB_API_URL`
The runner will automatically mask GitHub token formats it recognizes,
but sometimes a new pattern rolls out before the runner is updated to
recognize it.
