fix: Add required permissions for prerelease workflow

[Aaron ("AJ") Steers (aaronsteers)]

Summary

Fixes the /prerelease slash command workflow which was failing with:

Error calling workflow 'airbytehq/PyAirbyte/.github/workflows/pypi_publish.yml'. 
The nested job 'publish' is requesting 'contents: write, id-token: write', 
but is only allowed 'contents: read, id-token: none'.

The fix adds the required permissions to prerelease-command.yml so it can call the nested pypi_publish.yml workflow:

• contents: write - Required by the publish job for GitHub release uploads (only used on tag pushes)
• id-token: write - Required for OIDC trusted publishing to PyPI

Review & Testing Checklist for Human

• Test the /prerelease command end-to-end by commenting /prerelease on a test PR after merging. This is the only way to verify the fix works since the workflow requires the slash command dispatch infrastructure.
• Verify OIDC publishing succeeds - If PyPI's trusted publisher is configured to expect a different workflow filename (e.g., publish.yml instead of pypi_publish.yml), publishing will fail with an explicit error. Check the workflow logs if it fails.

Notes

• The contents: write permission is broader than strictly needed for prereleases (which don't upload to GitHub releases), but is required because the nested publish job declares it at the job level.
• This workflow allows prereleases from fork PRs (per previous discussion), which combined with these elevated permissions is a security consideration - only maintainers can trigger the command.

Received message in Slack channel #ask-devin-ai:

@Devin Please refresh my memory on this one. IIRC:
1. We may already have a PR but I don't recall why it wasn't merged.
2. The destination-side fix (probably in the CDK) is to not care if a namespace is provided as null. (Difference between _not_ being sent or being sent _as null_ is a JSON delivery nuance.)

> Hi everyone :wave:

> I’m trying to use PyAirbyte to move data from an S3 source to an Iceberg destination. The sync from the source to DuckDB cache works fine, but when loading into Iceberg, I’m getting an error saying that the namespace cannot be null.

> The issue is that the S3 source doesn’t seem to have any field or config option to populate the namespace, so I’m not sure how to handle this requirement on the destination side.

> Has anyone faced this before or found a workaround? Any guidance would be really appreciated. Thanks in advance! :pray:
