fix(release): finalize package metadata and gateway docs

[jxnl]

Summary

• update the wheel/sdist repository metadata from the former instructor-ai organization to 567-labs/instructor
• make release preparation reject stale repository metadata before artifacts are built or published
• include the compact OpenAI-compatible multi-model gateway base_url example from docs(from_provider): note OpenAI-compatible multi-model gateway base_url #2504 while preserving contributor authorship
• document the package metadata correction in the 1.15.5 notes

The package metadata defect was found by inspecting the exact wheel produced by the non-publishing readiness run after #2503 merged.

Included / superseded

• includes docs(from_provider): note OpenAI-compatible multi-model gateway base_url #2504 as the canonical compact docs update
• supersedes the broader DaoXE-specific docs PR docs: add DaoXE OpenAI-compatible gateway integration #2436 with the generic eight-line example

Both source commits remain separately attributed on this branch.

Note

Low Risk
Metadata, release script, docs, and tests only—no library runtime or dependency changes.

Overview
Updates published package metadata so project.urls.repository points at 567-labs/instructor instead of the old instructor-ai org, and records that fix in the 1.15.5 changelog.

Release preparation now reads that URL from pyproject.toml and fails fast with a repository URL mismatch if it still points at the wrong GitHub org, with a test covering the stale-URL case.

Docs add a short from_provider example for OpenAI-compatible gateways using base_url and a gateway API key (DaoXE as the sample endpoint).
