Part 1 of 3 to upgrade base image to Ubuntu:22.04
This must be merged before #9551 and cherry-picked into 2.4

Upgraded golang.org/x/crypto libraries to support diffie-hellman-group14-sha256. I also removed two Kex-Algorithms which should no longer be used for security reasons. This may cause some breakage for a very very small group of users. I would also recommend removing diffie-hellman-group14-sha1 in the very near future (v2.5) and give users plenty of warning.
