Group list not sorted alphabetically when attempting to add role grant for SAML group

[gaktive]

Issue description:
Per the known caveat with SAML auth providers, a user must select a group from the dropdown list of their own groups, when attempting to grant a role to a group via Rancher RBAC. In Rancher v2.5.9 this list was sorted alphabetically, in v2.6.0 it is not.

Business impact:
Some users have a very large number of groups 100+, and this makes it very difficult to find and select the right group when granting a group a role.

Troubleshooting steps:
N/A

Repro steps:

• Provision a Rancher v2.5.9 instance (I used github.com/superseb/tf-do-rancher2)
• Configure the keycloak authentication with the QA keycloak instance (https://github.com/rancherlabs/the-ranch/wiki/Authentication-Test-Setup-configuration#saml-with-keycloak)
• Reset password of alex.seymour@suse.com user in keycloak and log in to Rancher as the user (user is a member of 100 aseymourgroupX groups)
• Attempt to add a group grant at global/cluster/project level and observe the group list in the dropdown is sorted.
• Upgrade to Rancher v2.6.0 and attempt to add a group grant at global/cluster/project level and observe the group list in the dropdown is not sorted.

Workaround:
Is workaround available and implemented? No

Actual behavior:
Group list is not sorted

Expected behavior:
Group list is sorted

Reference: 3460

The associated PR fixes the initial sort of principals but not sort those returned from search, those should be sorted given the proximity to the search term
