Secure Shell (stable) updated to 0.74

[Mike Frysinger]

i've just released Secure Shell (stable) 0.74 which upgrades OpenSSH to 10.2 and includes mosh 1.4.0.

this mosh build is different from the one previously included since that only worked with NaCl, and the new one is built with WASM.  i've verified IPv4 & IPv6 both work.  it doesn't support relays though since those only work with TCP.

SFTP mounting semi-works again -- but you have to keep the window open for the life of the mount :(.
