[Bug] langtool.py not working with the CONTRIBUTING.md syntax & inaccuracies

What's the issue you encountered?

The syntax python3 dist/langtool.py create plugins/builtin/romfs/lang <iso_code> doesn't seem to be working anymore (error: unrecognized arguments: plugins/builtin/romfs/lang <iso_code>)

Instead you need to use
python3 dist/langtool.py create --langdir plugins/builtin/romfs/lang --lang <iso_code>
(or just python3 dist/langtool.py create --lang <iso_code> for everything)

Haven't tried the translate but ig the same issue occurs

Not PRing as i'm not sure if that's a me issue or nah (apparently been like this for a long time & no one complaining?) but doesn't look like it, can make one if needed

Also unsure if ISO 639-1 is the right format as it seems to be just 2 letters representing the language while the existing translation files are using ICU Locales (combination of ISO 639- lowercase language & ISO 3166- uppercase country)

Could also be nice to have an indication to put the language/country names in English & not in the language you're translating to while being prompted to enter those

How can the issue be reproduced?
