Currently if we choose text type, hasura still allows only 1 line input.
We should allow multiline text area for multiline input also.

Even better suggestion: Allow WYSIWYG and Markdown mode as options for users to switch. And we could allow for even more formats in future (like LaText)

This is really cool feature to have, because it'll allow rich text inputing right from the Hasura console UI without any need for external system.
