[web] Node 20 => 22 (#5562)

Contributors do not necessarily need to update to node 22, I tested that
the dev server works with node 20 also.

That said, if someone wishes to update - here is the dance I needed to
do on macOS. Garnish to taste and OS.
```sh
brew uninstall node@20
brew install node@22
brew link node@22
corepack disable
corepack enable
```
