Add manual-dispatch release workflow

[guysmoilov]

Summary

• Adds a workflow_dispatch GitHub Action (.github/workflows/release.yml) that automates the existing manual release process: bump __version__ in dagshub/__init__.py, commit to main, and cut a GitHub Release (auto-generated notes), which in turn triggers the existing python-publish.yml PyPI publish on release.
• Inputs: bump (patch/minor/major), explicit_version (overrides bump), release_title_suffix (appended to release title), draft (create as draft to review before publishing).

Test plan

• Run the workflow manually via workflow_dispatch with draft: true on a test version and confirm it bumps the version, commits to main, and creates a draft release without publishing to PyPI.
• Confirm python-publish.yml still fires correctly when the draft release is published.

Poem

A rabbit pressed “Release” with care,
Bumped the version into the air.
Tags were checked, the notes were spun,
A draft or launch for everyone.
Hop, hop—the new build has begun!
