chore!: require at least Go version 1.19

According to the Go support policy, major releases are maintained until
two subsequent major versions are released. Although Go 1.19 has
technically reached its end-of-life, it's worth noting that Debian
Bookworm currently only ships Go 1.19. As wfx remains unaffected by
this version, we're retaining compatibility for the time being.
