Rename file extensions

[coke]

Content here is so old, everything is .pm .pl .p6 - Update to use latest extensions.

There is no need, IMO, to keep the old URLs working (in an ideal world we would, but having the site follow standard and be navigable is more important IMO)

renamed internal files in lib/

To make the URLs work I can setup redirects from for ex. .pm -> .rakumod (At webserver level, no changes required here)

Edit: Oh I see that .pl isn't actually used on examples.raku.org but on links to source on github. Well, we can't really do anything about that.

Examples themselves don't seem to have the extension in links: https://examples.raku.org/categories/best-of-rosettacode/copy-a-string.html.

Ah, looks like public facing urls are already .html, so no worries.
