fix: attempt to fix codeql by installing deps (#106)

Codeql ci is currently failing. This might be because the workflow
is missing the c library needed to build luks2crypt. This installs
the dev libs for cryptsetup before running codeql. It also sets up
the go version in `go.mod` to ensure the toolchain is available.
