CLI-1398: ACLI does not copy the paths defined in installer-paths when {$name} is used

[camoa]

Describe the bug When using acli push:artifact to deploy code ACLI by default does not copy the compiled assets of the custom themes.

Acquia provided a solution per this doc: https://docs.acquia.com/acquia-cloud-platform/add-ons/acquia-cli/known-issues#section-artifact-does-not-include-front-end-build-assets

This does not work when the installer path is created like this in composer.json:

      "docroot/themes/custom/{$name}/css": [
        "type:npm-asset"
      ],

The files are not copied.

This type of installer path is important when using several tcustom themes like multisites and ACSF.

To Reproduce Steps to reproduce the behavior:

1. Add an installer-path (per the docs) to composer.json as shown in the description.
2. Add the necessary step (composer script called pre-acli-push-artifact) that compiles the them assets.
3. commit your changes
4. test acli push:artifact
5. Check the messages you will see a message like: "Forcibly coping /themes/custom/css"

Expected behavior ACLI should follow the standard use of installer paths and when finding {$name} in a path definition, it should create 1 entry per each subfolder or use some sort of * pattern to copy all possible ocurrences of the folders.
