[Release Enhancement] GHA Workflows to Update Versions Automatically

[cicoyle]

It would be nice to have an automated process that listens for a new tag to be pushed to the dapr/dapr repo that updates the version accordingly so we are always up to date on changes and can automate our release candidate testing. This should be automated to minimize the manual steps in the release process.

I propose adding a GitHub Action Workflow to dapr/cpp-sdk that listens for a new tag on the dapr/dapr repo and auto creates a Pull Request that updates that accordingly. Example proto updates - Protos will need to be updated/automated with this. Example #2

Note: Use the DAPR_BOT secret
