Support Ubuntu 26.04 in the new pre-built binary deb repository

[ArbitraryCritter]

Ubuntu 26.04 was released yesterday and you're well forgiven for notsupporting it yet. The 24.04 binaries seem to work perfectly in 26.04 though (installed by specifying the 24.04 repository), so it shouldn't require too much effort.

It's been a month now and 2 months since the beta came out. Where is official 26.04 support?

Looking for this as well.
