ValidationError on `lessLoaderOptions.javascriptEnabled`

2 days ago craco-less upgraded less-loader from 5 to 6 that has a braking change.

This causes the following error:

ValidationError: Invalid options object. Less Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'javascriptEnabled'. These properties are valid:
   object { lessOptions?, prependData?, appendData?, sourceMap?, implementation? }

There are 2 fixes that can be done:

1. Pin the version of craco-less to 1.16.0
2. Use the new lessOptions as described here

@ndbroadbent the issue wasn’t fixed, can you please re-open it?

As I mentioned earlier, there are only 2 options:

1. pin craco-less to 1.16.0 (uses less-loader@5) - a hotfix, done in #34
2. change the code here to work with less-loader@6 (see changes here) - the real fix, but can brake code for current users

@ndbroadbent I’m having the same error mentioned by @daniel-hauser also in the new version 1.15.0

ValidationError: Invalid options object. Less Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'javascriptEnabled'. These properties are valid:
