🐛 (backend) gitlab oicd userinfo endpoint

[AntoLC]

Purpose

Gitlab oidc was failing.

It is failing because the userinfo endpoint can return 2 content types:

• application/json
• application/jwt

impress/src/backend/core/authentication/backends.py

Lines 45 to 51 in 53267c7

	user_response = requests.get(
	self.OIDC_OP_USER_ENDPOINT,
	headers={"Authorization": f"Bearer {access_token}"},
	verify=self.get_settings("OIDC_VERIFY_SSL", True),
	timeout=self.get_settings("OIDC_TIMEOUT", None),
	proxies=self.get_settings("OIDC_PROXY", None),
	)

Gitlab oidc returns a json object, while Agent Connect oidc returns a jwt token.
We are adapting the authentication to handle both cases.

⚠️ The logout does not seem to work with the Gitlab oidc. I suggest we open an issue, maybe you will want to dig more on that @securitykernel ?

I proposed a small simplification using the "responses" library that we have in dev dependencies. Otherwise GTM!
