chore: add release-it + config

[webpro]

Pull Request Template

Description

Somehow I stumbled upon #22 and wanted to show what release-it could do for you:

• Auto-determine next version based on convention-based commits
• Generate and update CHANGELOG.md
• Git commit/tag/push
• Create GitHub Release
• Publish to npm
• Provide hooks to execute any commands where necessary (see this PR for an example)

Type of change

Please delete options that are not relevant.

• [ ] Bug fix (non-breaking change which fixes an issue)
• [x] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
• [ ] This change requires a documentation update

How to Test

Run npm install to add dependencies and then npm run release to see it in action. Make sure to not actually push/publish anything when only test driving.

Let me know if you have any questions or can help! Cheers.

👋 Thanks for your contribution! We have a slightly different release process as Microsoft, and I decided not to merge it.
