Merge branch 'new-project-mobile' into 'master'

New Project page improvements for mobile

## What does this MR do?

Redesigns the "Project path" fields on the New Project page.

## Are there points in the code the reviewer needs to double check?

Not that I know of, nothing I changed should break any other pages.

## Why was this MR needed?

The new project page was unusable on mobile because the project name text field didn't have enough space.

## What are the relevant issue numbers?

Fixes #18599.
