Be more lenient about version mismatches

[dominikh]

Currently, the user can experience the following:

module requires at least go1.24.1, but Staticcheck was built with go1.24.0 (compile)

This is needlessly pedantic. Language changes aren't introduced in minor releases of Go, so Staticcheck built with Go 1.24.0 should be able to check any module targeting Go 1.24.x.

The current behavior forces us to make new releases of Staticcheck just so we can rebuild the prebuilt binaries whenever a new minor version of Go is released, even when none of the fixes affect us.
