Fix (migrate-mv3): Send message

[ARajgor]

Changelog :

• I add sendMessage into the browser API wrapper to fix the Send Message error.
• Add scripting permission for adding element selector script injection.
• Switch to the execution tab after the block is executed.
• Tested on Windows and Chrome systems.

Let me know if any other things should be added.

Would this change allow for something like the below to work in a code block? chrome.runtime.sendMessage(extensionId:"extension-id", {message: "example"});

I'm hoping to communicate to other chrome extensions when it's their turn to automate things on their own pages since Automa can't access webpages owned by chrome extensions.
