[Inkscape-translator] Website: Code of Conduct is official

Dear fellow website translators,

Inkscape's Code of Conduct is now finally official - which means we can start translating it :)

Find the English page here: https://inkscape.org/en/community/coc/

Smaller changes might be made in the future (it's not written in stone), I'll keep you up to date :)

Kind regards + happy translating, Maren
