Block password reset if "Force SAML login" is enabled

@jcisio - thank you for this patch.

I have verified that it works as intended with the following configuration:
- Drupal 10.3.2
- PHP 8.3
- SAML Service Provider (saml_sp) 4.3.3
- SAML Drupal Login (saml_sp_drupal_login) 4.3.3

TESTING RESULTS

Prior to patch:

After applying patch:

Verified:

• "You are not allowed..." warning message
• Submit button is disabled
• Form cannot be submitted using keyboard "enter/return"

Moving to RTBC

Unfortunately, I think the pipelines build errors are preventing from merging in the issue fork. Will patch directly on the dev branch and push.
