[BasicUI] Some material icons missing

[lolodomo]

When implementing PR #2010, I discovered that some material icons were missing while they are supposed to exist, like for example this one: https://fonts.google.com/icons?selected=Material+Icons+Outlined:legend_toggle:&icon.set=Material+Icons&icon.query=legend+toggle

The reason could be that we rely on version 3.0.1:
https://github.com/openhab/openhab-webui/blob/main/bundles/org.openhab.ui.basic/package.json#L13

The last version is 4.0.0.
https://github.com/google/material-design-icons/releases/tag/4.0.0

if I changed the line in package.json to

"material-design-icons": "^4.0.0",

Then the build is failing, this version is apparently not found:

[INFO] --- frontend-maven-plugin:1.9.0:npm (npm install) @ org.openhab.ui.basic ---
[INFO] Running 'npm install' in D:\dev\openhab3\git\openhab-webui\bundles\org.openhab.ui.basic
[INFO] npm ERR! code ETARGET
[INFO] npm ERR! notarget No matching version found for material-design-icons@^4.0.0.
[INFO] npm ERR! notarget In most cases you or one of your dependencies are requesting
[INFO] npm ERR! notarget a package version that doesn't exist.

And

$ npm view  material-design-icons versions

[ '1.0.0',
  '1.0.1',
  '2.0.0',
  '2.1.0',
  '2.1.1',
  '2.1.3',
  '2.2.0',
  '2.2.1',
  '2.2.2',
  '2.2.3',
  '3.0.0',
  '3.0.1' ]

So more recent version is not published on npm repository :-(

https://www.npmjs.com/package/material-design-icons?activeTab=readme
google/material-design-icons#1129

one option to try would be to switch from the official repo to https://github.com/marella/material-icons
