Regex builder integrated into Regex Rule form

[DistantVoyager]

Environment

• Nautobot version: 1.5.18
• nautobot-data-validation-engine version: 2.0.0

Proposed Functionality

When adding a new regex validation rule, have some type of regex builder integrated into the form itself to help users to craft their intended regex.

Use Case

As a network engineer who is a novice with regular expressions, I want to be able to craft my desired regex within Nautobot when I am creating a regex validation rule without having to search online to figure out what I want to do.
