Observed behavior

In the administration there's no easy way to remove a channel from the community library - I need to delete the channel permanently to do so. Also after deleting the channel permanently when I go to the Community library page I can still see the channel card. When I click on the card I am getting the following error:

{
  "data": {
    "channel": [
      "Select a valid choice. That choice is not one of the available choices."
    ]
  },

Expected behavior

The expected behavior should be further discussed and specified.

Steps to reproduce the issue

1. Sign in to Studio at Unstable
2. Create a new channel, import content and publish it.
3. Click the Share button, select the 'Submit to community library' option and submit the form.
4. Approve the submission as an admin
5. Verify that the channel is displayed at the Community library page
6. Delete the channel as an admin

Usage Details

• Studio Unstable
• OS: Windows 11
• Browser: Chrome, Firefox

Reproduce the administration flow described in the issue, then inspect the Community library page and the /api/channelversion request after a submitted channel is deleted. Clarify the expected removal behavior with maintainers before changing anything; done should include a defined behavior for deleted channels and no invalid channel request or stale card.
