punycode module is deprecated

[JasonWeill]

When I run jlpm build with code at the tip of main, I see a warning:

(node:80138) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

This appears to be related to the punycode module bundled with Node, which has been deprecated since Node 7, in 2016. There is a third-party package of the same name that was most recently updated in October 2023: https://www.npmjs.com/package/punycode .

Remove all uses of punycode that are deprecated, and use the third-party package instead.
