Problem/Motivation
I'm getting the following error when trying to visit /admin/config/people/saml/saml:
AssertionError: assert($key_type instanceof KeyPluginBase) in assert() (line 164 of modules/contrib/samlauth/src/Form/SamlauthSamlConfigureForm.php).

This is fixable by adding the following use statement to the top of SamlauthSamlConfigureForm.php:
use Drupal\key\Plugin\KeyPluginBase;
Steps to reproduce
Attempt to load /admin/config/people/saml/saml
Proposed resolution
Add the use statement; I will open an MR and attach a patch in case anyone else is running into this issue and needs a quick fix :)
