[bug] global explore show repos of hidden org

[6543]

if you like to look at it - you get a 404 wich shows that the repo view handle rights in a correct way

To aid anyone looking into this, the problem comes from

gitea/models/repo_list.go

Lines 230 to 232 in 0842464

	if opts.AllPublic {
	accessCond = accessCond.Or(builder.Eq{"is_private": false})
	}

Because even though the repo is public, this condition doesn't take private orgs into account.
I have been mulling it over off and on, but truth be told that function is a tricky mess that needs refactoring imo
I'll keep thinking on it, but in the meantime someone else is more than welcome to swoop in and take it. 😅
