CI: Enable commit linting

[reb-dev]

Commits should have the following format:

<type> | <scope>: <subject>

Rules:

• type can be any of the following:

  Core, Component, Container, Utils, Styles - for core library changes
  Angular, React, Svelte, Vue - for wrapper related changes
  Website - for changes related to website content
  Dev, Shared - for changes to the demo app, dev tools or integrations
  CI - for CI/CD pipeline related changes
  Release - for release commits
  Misc - anything else
  

• scope should be the name of the component or feature being worked on in PascalCase
• Additional scope values can be added with | delimiter
• subject is a short description of the change in Sentence case
• A reference <#issue> may also be provided on the next line
• No leading or trailing whitespace in the header

Linter warnings:

• Scope is optional but encouraged for all types except CI or Release
• For Component type, scope should be one of the component names

Some examples:

Core | Utils: Refactoring shape rendering helpers
Component | Timeline: Fixing enter transition bug
Dev | Build: Upgrading rollup dependency
React | Autogen: Tweaking component lifecycle logic
Release: 1.4.0
Website | Gallery: Adding a new example
Website | Docs | Axis: Updating some property description

I went through this and I didn't find any obvious issues. Though this is more like a learning experience to me.
