In October 2019, Perl6 was renamed to "Raku".
The syntax is renamed to "Raku", however, I don't know if you prefer a name that also includes "Perl6", such as "Raku (Perl6)" or "Raku/Perl6".
I also add the new extensions (*.raku;*.rakumod;*.rakudoc;*.rakutest) and update the extension in the test file (highlight.raku).
Any inconvenience with this diff don't hesitate to notify.
