Json Form renders are uppercasing titles.

# Bug Report

## Summary

Json Form renders are uppercasing titles. It likely shouldn't be doing it by default. It's particularly bad when a measurement unit is provided, e.g. millimetres (mm) becomes MM.

## Expected behaviour

Don't uppercase

## Actual behaviour

They uppercase.

## Steps to reproduce

1. Use json renderers

## Screenshots or visual evidence (if applicable)

## Environment

## Additional context

That happens through a CSS directive. `text-transform: capitalize;` - you can overright these with css, but its normal behaviour should be do-nothing.

Start by locating the Json Form renderer styles and the CSS rule applying text-transform: capitalize. Verify the change with a renderer using a measurement unit such as millimetres (mm); done means titles preserve their original casing by default.
