test_external_idp: update code for selenium 4.10

The integration test is using selenium web driver to simulate a
user authentication with an external IdP. The user performs kinit
and is provided with a URL where he needs to authenticate.

The test was written for selenium API 4.9 and must be adapted to
the changes introduced in 4.10:
- the headless method has been deprecated
- executable_path argument has been deprecated
