Hebasto and Stepanov did not add their signatures to SHASUMS.asc
acquired from the Bitcoin website but did sign the releases in
guix.sigs.
Keys who did not sign the current release were removed as they haven't
been signing for some time.
New keys added for 0xb10c (Core), Emzy (Electrum) and Guggero (LND) were
added and they have been signing every release since 22.0 (oldest
possible release that has detached signatures in guix.sigs).
There are 9 keys present now, 6 entities that are adding their
signatures to the detached signature file and 4 that are required for
the verification to succeed.
Other keys that signed the current release and are considered to be
added if any of the current signers quit: kvaciral (since 23.0),
TheCharlatan (since 24.1), willcl-ark (since 25.0), m3dwards (since
26.0), pinhead (since 26.0)
