Fix bugs

Fixes the following bugs:

• Requesting the deployment status may return 404 due to the GitHub API for deployment status not being available immediately after the deployment is returned, retry if the deployment status returns an error to fix this.
• Default interval was set to 1ms, now to 5 seconds as documented.

Add SHA

Adds the SHA of the commit being deployed as an argument. This avoids issues due to the GITHUB_SHA not matching the commit being deployed.
