incorrect OIDC redirect URI

[I3urny]

The documentation lists /oidc_authorize as the OIDC redirect URI, when it really should be /oidc-authorize.

The docs:

iris-doc-src/docs/operations/access_control/authentication.md

Line 176 in ef896f9

On the OIDC provider, the URI to set is `/oidc_authorize`.

The actual route in the app:

@login_blueprint.route('/oidc-authorize')
