[PRQ#45882] Deletion Request for bootstrap5

MarsSeed [1] filed a deletion request for bootstrap5 [2]: One-time effort orphan package from 2021, for the Bootstrap JavaScript front-end library. Current pkgver is for a beta release. It is not useful to have this on AUR. As this should be delivered to the web browser client by a server backend, and the packaging method depends on which web backend server framework is used.
