Describe the bug

When getting multiple keys in a path using wildcard, the resulting environment variables have their case transformed to uppercase.

To Reproduce

with:
    secrets: |
        secret/data/ci/aws * | MYAPP_ ;

The key accessKey will be created as MYAPP_ACCESSKEY.

Expected behavior

The exported environment variable should retain the key case, e.g. MYAPP_accessKey.
