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.

The -dropgodebug=key flag drops any existing godebug lines
with the given key.

The -use=path and -dropuse=path flags
add and drop a use directive from the go.work file's set of module directories.
