Invalid option specification (Namespace: 'aws:elasticbeanstalk:environment', OptionName: 'Domain'): Unknown configuration setting.

### Description

Briefly describe the bug you are facing.

Even after deleting all "Domains" from all relevant files/configs I still get the error above. I am using. custom domain, but any references to it have been deleted. Please help.

### Steps to reproduce

Provide steps to replicate. This should include: exact `ebcli` commands, any relevant configuration files(sanitized), platform version, region, as well as any additional information you think is relevant.

### Expected result

Describe what you expected.

### Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Mac OS 15.0.1
2. EBCLI version:
```

eb --version
EB CLI 3.21.0 (Python 3.12.4 | packaged by Anaconda, Inc. | (main, Jun 18 2024, 10:07:17) [Clang 14.0.6 ])
```

Start by reproducing with `eb deploy --debug` and inspecting `.ebextensions/node-settings.config`, along with the `deployops.py` and `commonops.py` entry points named in the traceback. Done means identifying why the `Domain` option is submitted despite the shown configuration and documenting or correcting the behavior so deployment no longer reports the unknown setting.
