JSON input transformation editor is very narrow

[DavidHopkinsFbr]

Describe the bug

When using the table Insert UI with the "JSON (text/plain)" input transformation, the provided editor window is very narrow compared to standard text field entries.

To Reproduce

Steps to reproduce the behavior:

1. Create a table with a LONGTEXT column with "Browser display transformation" set to "JSON (text/plain: JSON)" and "Input transformation" set to "JSON (text/plain: JsonEditor)". Create a second column of varchar(255) or TEXT type.
2. Click on 'Insert'
3. Observe that the JSON editor box is extremely narrow compared to other long-text fields.

Expected behavior

I'd expect that JSON fields would be given about the same amount of UI width and height as other long-text types. A pretty-printed JSON structure is likely to have reasonable line lengths and a non-pretty-printed JSON literal will likely be quite wide.
