Bulk Access Management processes are executable without selecting any options in step 2

[maxsullivan]

Describe the bug

Dspace version 7.6.2

A user can execute a bulk access management process when they have selected any item in step 1 without having selected an operation in step 2.

To Reproduce

Steps to reproduce the behavior:

1. Go to the bulk access management page and select an item or collection in step 1.
2. Skip step 2 and execute the process.
3. The process will start and then fail.

Expected behavior

The Execute button should not be active until the user has selected an operation in step 2.

This sounds like a front-end bug (as the button is not disabled when it should be). So, moving this ticket to the frontend & to our maintenance board for 7.x & 8.x
