var on assets path ?

I can't find a simple way to use the package name to create a path. In order to use it as an asset.

here is a part 'prepare' of .releaserc.yml

prepare:
  - path: '@semantic-release/exec'
    prepareCmd: "echo '__version__ = \"${nextRelease.version}\"' > $CI_PROJECT_NAME/version.py"
  - path: '@semantic-release/changelog'
    # Create or update the changelog file in the local project repository
  - path: '@semantic-release/git'
    # Push a release commit and tag, including version files
    # Do not forget to put `[skip ci]` to avoid CI/CD infinite loop
    message: 'chore(release): ${nextRelease.version} [skip ci]'
    assets: ['CHANGELOG.md', '$CI_PROJECT_NAME/version.py']

Here :
assets: ['CHANGELOG.md', '$CI_PROJECT_NAME/version.py']
i cant' use env var like this, there is another way ?

Note:
prepareCmd work well with $CI_PROJECT_NAME.

Start with the .releaserc.yml example, comparing how prepareCmd expands $CI_PROJECT_NAME with how the git plugin reads the assets list. Determine whether asset paths can use the package or environment name, and consider the configuration behavior needed so the generated version.py path is accepted.
