Tooltip to inform of reason for disabled action

[CakeCrusher]

Note

I added the following TODOs:

• {/* TODO: incorporate localize */} I did not incorporate the translations for this tooltip message
• {/* TODO: refactor to use https://atomiks.github.io/tippyjs/ */} Using this custom tooltip UI is convoluted tippyjs could significantly simplify this.

Summary

when creating an action for an assistant the button is sometimes disabled if the assistant has not yet been created therefore without an explanation of why it's disabled this PR informs the user of why the button is disabled.

Testing

you click on assistance and then you go to assistant builder where you will see that for an assistant that is already created the action button is activated but if you try and create a new action the action button defaults to disabled that is when the tooltip shows why it is disabled.
