Build static linux binary on Ubuntu 22.04

On Github Actions, ubuntu-latest is now ubuntu-24.04, which uses a new
version of glibc (2.39). As a result, the binaries do not work on
systems using an older version of glibc, like Debian Bookworm.

Continue to build the static linux binary on Ubuntu 22.04 (with glibc
2.35) for better compatibility.
