modfile: update toolchain syntax

Final revisions for Go 1.21: lock down the toolchain syntax to use
'toolchain default' instead of 'toolchain local', to avoid confusion
with 'GOTOOLCHAIN=local'; 'toolchain local' does not always mean
the same thing.

Also remove the prefix-go1.2.3 toolchain name form, leaving only
go1.2.3-suffix. There is no need to have two different forms, and it's
confusing.

For golang/go#57001.
