Bump go-github to v63

[Moser-ss]

Updates the dependency go-github from v62 to v63. Fix the breaking changes where CreateOrUpdateCustomRoleOptions has been renamed to CreateOrUpdateCustomRepoRoleOptions and roleID has been changed from type string to int64

The update is necessary to implement the feature requested in the issue #2137 because the repostiory_property is only available in the go-github v63

I'm not sure why the new merge UI isn't giving me the chance to approve automated checks, but this builds and lints successfully for me locally. There's a test failure that also crept into the main branch somehow and is unrelated.

Thank you!
