Pruning dangling entries

[lexisother]

If I have a site with entries in various sections, and I delete the site by removing it from the project config and running project-config/apply, the entries will stay in the database and gc/run will not delete them. I know this is a rather unconventional way to delete a site (typically you also delete all related content through the UI) but I am debugging a multi-site setup and git checkout -- config is the easiest way to reset the site to the pre-modified state.

Is there any way to clean these dangling entries up from the database?
