The go.mod toolchain directive, introduced in Go 1.21, can be leveraged to
execute scripts and binaries relative to the root of the module when the
“go” command was executed within the module. This applies to modules
downloaded using the “go” command from the module proxy, as well as modules
downloaded directly using VCS software.
