Only honor //go:build language version downgrades if the version specified is 1.21 or greater. Before 1.21 the version in //go:build lines didn't have the meaning of setting the file's language version. This fixes an issue that was appearing in GOPATH builds: Go 1.23 started providing -lang versions to the compiler in GOPATH mode (among other places) which it wasn't doing before. For example, take a go file with a //go:build line specifying go1.10. If that file used a 1.18 feature, that use would compile fine with a Go 1.22 toolchain. But, before this change, it would produce an error when compiling with the 1.23 toolchain because it set the language version to 1.20 and disallowed the 1.18 feature. This breaks backwards compatibility: when the build tag was added, it did not have the meaning of restricting the language version.
