How to the make 'Landing page URL' field optional

It's best practice for users to create campaign links with both a landing page and campaign code. This allows us to validate the landing page and keep an accurate record of campaign links.

However some users might need to create campaign codes before the landing page URL has been created or chosen, and others may not want to include the landing page field at all in Uplifter.
