chore: GH Action added (#107)

* Added github action to call vector webhook url

* Removed 'docs-to-vector' branch from GitHub Actions workflow trigger

* Refactor GitHub Actions workflow to enhance webhook payload structure and add support for 'docs-to-vector' branch. The payload now includes repository name and uses HMAC for signature verification.

* Remove 'docs-to-vector' branch from workflow triggers in GitHub Actions configuration

* Update GitHub Actions workflow to conditionally send webhook payload only if VECTOR_WEBHOOK_URL is set
