mrc-4125: Update to Node 20.

This is a mostly straightforward upgrade. Just a few notes:
- The lockfile format has changed so gets rewritten entirely.
- webpack is bumped to the next dot release. This adds a workaround
  caused by Node switching to OpenSSL 3, which drops md4 as a hash
  function (webpack/webpack#17628).
- node-sass did not build on the new node so had to be updated.
- I've updated playwright to take advantage of its added support for
  installing dependencies on Debian, removing the hardcoded list of
  packages we had to install.

There's a whole bunch of updates we could do to our NodeJS dependencies,
but I've left that for a later point since they aren't urgent or
necessarily trivial.
