Remove Strongbox

[MooseExplorer637]

As Strongbox has now been sold to a shady company with a bad track record, I propose that we remove it completely from the recommendations. I believe KeePassium could be a potential alternative that has recently done some exiting stuff, such as adding support for passkeys and a proper Mac app, as well as having an external security audit.

Going to give this a few more days to just see how this unfolds and if we get any updates, but yes I'm in the same court of removing as soon as I saw the announcement yesterday as well. Very sad stuff, my favorite KeePass client on any OS.
