[bug#57491] [PATCH] patch series: Update Raku ecosystem

[Daniel Sockwell via Guix-patches via <guix-patches@gnu.org>]

The fourth (and, for now, last) patch in this series updates Rakudo,
the primary Raku compiler.

Finally, I also want to note that one of the major changes in the Raku
ecosystem in the last few years is Raku's name: Raku was previously known
as "Perl 6" and the Guix module name refers to by that old name.  I'm not
sure if there's any way to update Guix's name (or add an alias?) without
breaking things.  But I wanted to bring the issue to the attention of 
people who might know the best way to proceed.

I look forward to any feedback you might have and/or to being able to
`guix install` an up-to-date version of Raku soon!

Best,
Daniel
