Add simple 'checks' workflow for PR and Merge events

This workflow automates the following tasks:

1. On pull requests to the 'main' branch, it runs a basic CI check.

2. On pushes or merges to the 'main' branch, it runs the CI check. If successful, it triggers the 'release' job, which performs the following actions:
   - Determines the current version (e.g., v1.0.1) and increments it to create a new version (e.g., v1.0.2).
   - Creates a new version release with the updated tag (e.g., v1.0.2).
