chore: Update source-declarative-manifest to use python-connector-base 4.0.1-rc.1 (do not merge)

Summary

Updates the source-declarative-manifest Dockerfile to use the new python-connector-base:4.0.1-rc.1 image that includes Python 3.11.13 security patches (upgrading from Python 3.11.11). This change targets the new base image created in airbytehq/airbyte#62864.

⚠️ Important: This PR is marked as draft because the target base image is not yet published to DockerHub.

Review & Testing Checklist for Human

Risk Level: 🟡 Yellow (2-3 items to verify)

• Verify base image is published: Confirm that docker.io/airbyte/python-connector-base:4.0.1-rc.1 is available on DockerHub before merging
• Add SHA256 hash: Once the base image is published, add the SHA256 hash back to the FROM line for security/reproducibility (following the pattern from the original Dockerfile)
• Test source-declarative-manifest build: Verify that the source-declarative-manifest image builds successfully with the new base image
• Test manifest-only connectors: Verify that at least one manifest-only connector still works correctly with the updated base image

Recommended Test Plan:

1. Wait for base image publication
2. Update Dockerfile with SHA256 hash
3. Build source-declarative-manifest image locally
4. Test with a simple manifest-only connector (e.g., source-hardcoded-records)

Notes

• This change is part of a security update to address vulnerabilities in Python 3.11.11
• The original Dockerfile included a SHA256 hash for the base image, which should be restored once the new image is published
• The source-declarative-manifest image is used by many manifest-only connectors, so this change has broad impact
• CI checks may fail until the base image is published

Original prompt from David Gold:

Hi Devin. Can you do some research for me in the airbyte and airbyte-cdk repositories? I'm working on patching some security vulnerabilities in python 3.11.11 in the base Docker images used for connectors. As part of that change, I plan to create a new python connector base image. 

Now I want to create a new source declarative manifest base image that will use the patched python base image. The Dockerfile of which appears to be defined in the cdk repository, though please verify this. It also appears that that image is referenced in the airbyte repository in order to build connectors. Can you verify all of this information and figure out everything that must be done for this change? Come up with a plan and share it with me - don't open a PR yet
