Create GH Actions workflow for templating an event

[zenlex]

This project pulls events from markdown files in the repository dynamically and merges them with events pulled from the Meetup API. New events can be created simply by merging markdown files where the path is /pages/events/{event-slug}/index.md. The action should be configured for manual triggering with these inputs:

• title
• date
• author
• location

The action should:

• generate a url safe slug
• checkout the current content/events branch
• create an {event-title}.md file at /events
• the index.md file should contain frontmatter in the following format:

---
- title: {user title from workflow trigger}
- author: {user author from workflow trigger}
- slug: {generated based on title}
- date: {user provided date as ISO-8601 string}
- location: {string}
- content-type: "blog | project | event" (each document will only be one type)
- publish: true | false
---

• commit the changes and push to content/blog
• generate pr from content/blog -> dev
• bonus points if it redirects to the newly created markdown file
