Support Node 18 with Drupal 10

Additionally to upgrading the dependencies, this patch captures the latest Bootstrap _variables.scss and imports list. Additionally it removes redundant items already captured through package dependencies, such as sass and node-sass (captured via sass-loader).

Need to support Radix 4 just slightly longer for our projects. Patch #6 successfully applies to Radix 4.13.0. Those wishing to apply this patch and update their sub-themes may find these instructions → helpful.

Thanks for your work jcandan, this is not actively supported, so could you provide a MR? and someone need to test it afterwards

No longer supported/outdated, closing - merged the MR. thanks
