[feature] Allow environment variables in bucket name

[JP-Ellis]

I have a use case whereby I would like to allow a variable in the S3 bucket name. For example:

steps:
  - label: Step 1
    env:
      ENVIRONMENT: dev
    plugins:
      - nienbo/cache#v2.4.15:
          backend: s3
          id: python-312
          key: v1-{{ id }}-{{ checksum "pyproject.toml" }}
          restore-keys:
            - v1-{{ id }}
          compress: true
          s3:
            bucket: s3-cache-$ENVIRONMENT
            save-cache: true
          paths:
            - .cache/pip

I have tried using $ENVIRONMENT, $$ENVIRONMENT as well as {{ env.ENVIRONMENT }}, but none of the options seem to work unfortunately.

Is this supported through some other means? Or if not supported, could this be added?

it works for me. try:

bucket: "s3-cache-${ENVIRONMENT}"`
