FilterUninstallValidator stops uninstall when module being uninstalled is only one using a filter format

Problem/Motivation

When trying to uninstall mailchimp_campaign, FilterUninstallValidator returns an error because mailchimp_campaign is using that filter. It's good to check whether other modules are using that filter, but since we are uninstalling mailchimp_campaign, it seems like it should get through the validation without worrying about its own filter.

The error from #2585215: Mailchimp Campaign cannot be uninstalled →

The following extensions will be uninstalled: mailchimp_campaign
Do you really want to continue? (y/n): y
exception 'Drupal\Core\Extension\ModuleUninstallValidatorException' with message 'The following reasons prevents the modules from [error]
being uninstalled: Provides a filter plugin that is in use in the following filter formats: MailChimp
campaign'

And from the duplicate issue 🐛 Impossible to uninstall a module that provides a config override for a filter Closed: duplicate .
The Filter module implements an UninstallValidator that prevents a module from being uninstall if it provides a filter plugin that's actively being used by some filter. To resolve it, a site admin must simply remove the filter plugin from any active filters.

However, if the filter plugin is enabled on a filter by means of a configuration override, then there is no way to remove it. If the module providing the override is the one you want to uninstall, it's impossible.

We run into this issue on Drupal 9.5.x with amazon_onsite contrib module which provide a CKEditor 4 plugin which was used in one of our editor and text filter configs.

Patch from #12 applied fine and fixed this uninstall issue in our case. When our internal QA process is finished I could give feedback with Drupal 10.1.x.
