Fix asset path issue for "compound-design-tokens" package

[menturion]

The fix given here #26069 does not work if one clone the compound-design-tokens package separately and link it within the matrix-react-sdk, because the regex /@vector-im(?:\\|\/)compound-(.*?)(?:\\|\/)/ does not match the paths in case of a cloned & linked package due to the missing substring @vector-im, see below:

Resource paths (on Windows) are e.g. ...

• Not linked package
  resourcePath: C:\src\matrix-react-sdk\node_modules\@vector-im\compound-design-tokens\icons\chat-solid.svg

• Cloned & linked package
  resourcePath: C:\src\compound-design-tokens\icons\chat-solid.svg

Problem:
The main problem is not whether absolute vs relative paths but that the compound-design-tokens package does not have a dist or res subfolder to serve the assets so that the existing regex /^.*[/\\](dist|res)[/\\]/ does not match.

Solution:
The solution is to add the missing root folder name for the assets to the above regex, with ...
/^.*[/\](dist|res|compound-design-tokens)[/\]/

I have tested this for both scenarios (linked/not linked) on Windows and it works with the regex statement:

const prefix = /^.*[/\\](dist|res|compound-design-tokens)[/\\]/;

The full part regarding compoundImportsPrefix is in this case obsolete and can be removed in the webpack.config.js.

This looks sensible to me.

However, I'm afraid we don't accept contributions signed off under a pseudonym, per CONTRIBUTING.md, so we'll need your real name to be able to accept this.

If you prefer, you can provide this privately by emailing [email protected], though our contributing guide doesn't seem to mention this (#26654).

Hi Richard, many thanks for the info and your support.
I have filed the issue here #26657 which should be fixed IMHO.
