updated _automation/main.go script to prefer commits tied to a latest…

… release, if it exists. Added a README.md for this file. Added a subcommand called 'run-tests' which will run 'go test' against every grammar's 'binding_test.go' file.

 This Go program automates the process of checking and updating grammar versions for various programming languages. It targets specific grammars defined in a JSON configuration file and supports operations like checking for updates and performing updates.
 
+If a grammar repository includes a Release, this updater prioritizes updating to the latest release rather than the most recent commit. In cases where the repository lacks releases, it defaults to using the latest commit. 
+
 ## Features
 
 - **Check for Updates**: Scan through defined grammars and check if there are new versions available.

+## Test After Updating
+Once you've updated a grammar, it is important to test that the binding tests still pass (`binding_test.go`). This can be automated by running the following command, which will run `go test` against every grammar:

+```bash
+go run ./_automation/main.go run-tests
