site: dep updates for bugfixes and webpack 5

[chappjc]

The audit failures came up recently, and the postcss vuln fix is available with stylelint now and the css-minimizer-webpack-plugin>svgo>css-select-css-what fix is available.

The package-lock.json update is committed as a dummy user in a separate commit, as I have done in the past.

A notable change from the Dart sass update is that it now complains about bootstrap using the / operator instead of math.div. This is fixed now in bootstrap 5, but it's just a warning. See twbs/bootstrap#34051 for discussion on this fairly contentious sass change. Still, we should look into bootstrap 5 at some point.

This also removes webpack-dev-server as that was never used with dex (or dcrdata where this was taken from).

@martonp I should have put this up sooner but I was waiting for some upstream fixes. Still not everything I was hoping for though. In any case, CI on your PR ended up working so it looks like it was a transient issue after all.

With these npm updates, I like to put the package-lock.json diff in a separate commit with a fake user as the author since otherwise it can be misleading when looking at commit history.

@chappjc Why is it misleading?

In terms of actual work done on a repository.

svgo just got patched so now npm audit passes.

imo super not important, besides, there would be not repository w/o you
imo don't waste you time on fake users

Builds and runs well. Also see the deprecated warnings about slashes.
