The list is produced from the output of `go mod graph`. You can see the
code that builds the list here:

https://github.com/openbsd/ports/blob/master/infrastructure/lib/OpenBSD/PortGen/Port/Go.pm#L162-L191

As for generating the list, if you set MODGO_MODNAME (this is always the
"module" line from a projects go.mod file) and MODGO_VERSION (the latest
semver tag for a project) you can run "make modgo-gen-modules" to
produce the needed MODGO lines. I always do:

make modgo-gen-modules > modules.inc

Because the list is usually long.

Mod files are used by Go for dependency resolution. It needs multiple
versions as part of this.
