Pull request overview
This PR implements a GitHub Actions workflow to automatically trigger cache revalidation when MDX documentation files are updated. When changes to MDX files in the fern/ directory are pushed to main, the workflow calls a revalidation API endpoint to refresh the affected pages.
Changes:
- Added a new GitHub Actions workflow that triggers on pushes to main when MDX files in
fern/are modified - Implemented logic to detect changed MDX files, transform their paths, and send them to a revalidation API endpoint
- Included error handling and response validation for the API call

Description
Now that we have a revalidation endpoint, this GHA checks for changes in MDX files that were just merged to main. Then it fires one call to the revalidate endpoint in the docs site and echoes the response.
