Device Type images can not be deleted via UI

[m2martin]

NetBox version

v3.0.1

Python version

3.9

Steps to Reproduce

1. Create a Device Type or edit an existing one and add a front and/or rear image
2. Device Type is created or edited successfully
3. Edit Device Type in order to delete/remove the front/rear image

Expected Behavior

I expect a link or any other control element to delete the image or to mark the image to get deleted on save.

Observed Behavior

No control element to delete an image is visible.
Currently, the only way to remove/delete images seems to be nbshell.

I just want to call out that we've had a similar issue in the past (#5595), although this seems to be unrelated.

It looks like we lost the display and deletion functionality when the form widget was updated for Bootstrap 5.

I guess, too.
