Enabling the selection of multiple users for common actions in the users section

Is your feature request related to a problem? Please describe:
Currently, admins are unable to select multiple users to perform common actions such as deleting or disabling their accounts in the users section. This limitation causes inconvenience and inefficiency for administrators managing user accounts.

Describe the solution you'd like:
I suggest implementing a feature that allows administrators to select multiple users simultaneously in the users section and perform common actions like deleting or disabling their accounts. This feature would streamline user management processes and improve overall efficiency.

Describe alternatives you've considered:
One alternative could be manually performing actions on individual user accounts, which is time-consuming and prone to errors, especially in environments with a large number of users. Another alternative might be creating custom scripts or using third-party tools, but these solutions may not integrate seamlessly with Nextcloud and could introduce additional complexities.

Additional context:
Adding this feature would enhance the user management capabilities of Nextcloud, providing administrators with more flexibility and control over user accounts. It would contribute to a smoother and more efficient administrative experience within the platform.

Start by tracing the existing users section and its single-user delete and disable actions. Define the supported bulk actions and verify that administrators can select multiple users and apply those actions consistently, including appropriate handling of permissions and failures.
