add possibility to delete a tag

[FrancYescO]

Is your feature request related to a problem? Please describe. after deleting an image the tag will remain forever and there is no way to delete, neither garbage collector deletes it if there are no images under the tag

Describe the solution you'd like add a button to delete a tag and all associated images, here a way on how that can be done via apis https://stackoverflow.com/a/71580038/5180992

also can be useful a button to call the garbage collector, but i assume there is no way to do via apis
