[Find Forms] Replace MomentJS with date-fns

[randimays]

Description

Application: Find Forms

According to the MomentJS Docs, MomentJS is a legacy project in maintenance mode. This means no new features or capabilities, no major changes, possibly no bug/quirk fixes, and no bundle size fixes.

MomentJS is a significantly larger JS library than alternatives like date-fns. We should migrate to date-fns to improve package size for our application. We may see tiny improvements in performance, but the biggest gain here is moving to a package that is actively supported/improved and more likely to have support for new browsers going forward.

User story

AS A PO/PM for Find Forms I WANT a JS library that is not obsolete/in maintenance mode SO THAT the code is in a package that is active supported/improved, will be maintained and fixed if issues arise, and more likely to have support for new browsers going forward.
