#1986 seems to break setting base URL.

What I did:

auth = AppAuthentication(int(os.getenv("GITHUB_APP_ID")),
                         t,
                         int(os.getenv("GITHUB_APP_INSTALLATION_ID")))
g = Github(base_url="https://test.somegit.com/api/v3", app_auth=auth)

When I turn on debugger, the base URL for requester seems to be set to api.github.com. Lmk if I am doing something wrong here, thanks!

Looks like the Requester does not pass the base url to GithubIntegration:

PyGithub/github/Requester.py

Lines 375 to 379 in c7e3ae9

	def _get_installation_authorization(self):
	assert self.__app_auth is not None
	integration = GithubIntegration.GithubIntegration(
	self.__app_auth.app_id, self.__app_auth.private_key
	)

PyGithub/github/GithubIntegration.py

Lines 19 to 26 in c7e3ae9

	def __init__(
	self,
	integration_id,
	private_key,
	base_url=Consts.DEFAULT_BASE_URL,
	jwt_expiry=Consts.DEFAULT_JWT_EXPIRY,
	jwt_issued_at=Consts.DEFAULT_JWT_ISSUED_AT,
	):

I took a stab at it (big thanks for the feature add from #1986 btw): #2425
