Update minify-html and minify-js

[cormacrelf]

Fixes build issues related to wilsonzlin/minify-html#166. In particular, building trunk was failing completely under Nix, which disallows internet access during builds.

Technically would have been solved just by updating minify-html, but the two packages are from the same author. So whatever, why not.

@cormacrelf I had to revert this PR, because it breaking the output:

There's also the thing that it pulls in lighteningcss, which currently is only released as a pre-release. That might also become an issue, but unless someone touches the Cargo.lock file, that should hold. Still I think it's far from optimal.

I raised an issue for the lighteningcss release: parcel-bundler/lightningcss#662

I played a bit with that … it looks like minify-js is the problem. 0.5.x works, while 0.6.0 doesn't.

Sorry for adding unnecessary bumps to the PR that broke it! "Why not" indeed.
