The -fmt flag reformats the go.work file without making other changes.
This reformatting is also implied by any other modifications that use or
rewrite the go.mod file. The only time this flag is needed is if no other
flags are specified, as in 'go work edit -fmt'.

The -godebug=key=value flag adds a godebug key=value line,
replacing any existing godebug lines with the given key.
