Issue Summary: 

Forge CLI 13.3.0 introduced a new server-side pre-deployment manifest check, tied to the newly announced approval-workflow feature (published in CHANGE-3376). As part of this change, forge deploy now invokes a new validation endpoint before the actual deployment step begins.

If a manifest contains environment variables, these are not being interpolated before being sent to the server side lint check, meaning developers are seeing false positives of the `MANIFEST_INVALID_RULE` error.

Steps to Reproduce

1. Use 13.3.0
2. Run `forge deploy` with a manifest that uses environment variables. 

Expected Results

Environment variables are interpolated before linting occurs.

Actual Results

There is a false positive MANIFEST_INVALID_RULE error. 

Workaround

The server side linting can be skipped by deploying with `forge deploy --no-verify` or you can temporarily downgrade to v13.2.0 until the next cli release.
