Modernize ember-simple-pagination Addon

[vstefanovic97]

This Addon needed some love so I did a full refactor, it would be nice if we could get this merged and have a Major release

Work done

• Converted the simple-pagination component to glimmer
• Converted the Addon to v2 addon format (Upgrading all deps along the way)
• Updated the docs with angle bracket invocation and modern usage example

Breaking changes

• Drops all Node versions below 14
• Drops all Ember versions below 3.24
• dataTestSelector is no longer accepted as an argument on simple-pagination component (it should be provided as an attribute as not we have ...attributes on the containing div)

Important notes

• Updated ember-try to target correct ember versions above >= 3.24
• Deleted Unit tests as invoking component in that way is no longer supported (I think we should be good with the coverage we have in integration tests)
• Changed the version in package.json to 2.0.0 to signal breaking change
