ghinstallation returns app JWT in error responses

Quick fix

GHSA-h4q8-96p6-jcgr — github.com/bradleyfalzon/ghinstallation: upgrade to the fixed version with the command below.

go get github.com/bradleyfalzon/ghinstallation@v2.0.0

Details

### Impact

In ghinstallation v1, when the request to refresh an installation token failed, the HTTP request and response would be returned for debugging.

https://github.com/bradleyfalzon/ghinstallation/blob/24e56b3fb7669f209134a01eff731d7e2ef72a5c/transport.go#L172-L174

The request contained the bearer JWT for the App, and was returned back to clients. This token is short lived (10 minute maximum).

### Patches

- This has already been patched in d24f14f8be70d94129d76026e8b0f4f9170c8c3e, and is available in releases >= v2.0.0.
