Add a delete button from plugin, so no need to get to linkding page to delete the url

Some websites have parameters(https://a.com/b/c?a=1), and because of the extra parameters, the url still could be bookmark mistakenly even https://a.com/b/c is already bookmarked.

Some of the parameter could mean different page, but some are not, I don't have a good idea to eliminate the problem.

1. https://a.com/b/c?pageid=4yh98aseghv means a identical page
2. https://a.com/b/c?page=1 is meanningful but could be duplicate
3. https://a.com/b/c?trackid=9473gf could be some advertisement tracker running by some website, not meanningful for bookmark
