Option to expand instructions for Assistant

[AntoJustinT4D]

In the feature provided to create AI assistants inside Glific itself, there is no provision to expand the instructions text box which is very small and not very conducive towards longer instructions.

In the Open AI playground, there is an option to expand the textbox where we can enter longer texts and review it easily. This provision is currently not available inside Glific.

There should be a provision to be able to expand the typing/reading area for the instructions in line with the way in which it is available in the Open AI playground.

Closing this, since a PR for this is already merged and will be included in next deployment.
