3299 security issue

Closes opengeoweb/opengeoweb#3299 (closed)

In this MR:

• Updated starlette and fastapi libraries following the taf aviation BE
• Needed to remove None as definition of the return of the delete_view_preset endpoint for all tests to pass (the check for 204 returns has been changed in the new version of starlette)

How to test:

• Verify no changed functionality
• Important! Carefully check to which OAUTH2_USERINFO value you use, as in the current readme the new cognito url already is shown
