[Feature] Move Dependency to Version Catalogue TOML

[DissonantAU]

Version Catalogue should be moved to gradle/libs.versions.toml to better follow recommended conventions:
https://docs.gradle.org/current/userguide/version_catalogs.html

• Move dependencies from settings.gradle to libs.versions.toml
• Move Plugin Versions from Build Files to libs.versions.toml

The move of plugin version also makes it easier to update those

[DissonantAU]

I've created a fork implementing this here:
https://github.com/DissonantAU/TouchPortalPluginSDK/tree/develop-dependencylib

Fork is up to #65 as newer commits cause build to fail

[DissonantAU]

Created another Branch based on the #72 branch
