Not compatible with Download Timely All-in-One Events Calendar v3.0+

[kimcoleman]

Describe the bug
v3.0+ of Timely All-in-One Events Calendar has moved to a SaaS-like model where events are created in their service, rather than within the WordPress site.

Users can then display those events using shortcodes within the WordPress site.

Our direct integration for this plugin is no longer needed.

Users should rather leverage the content protection settings in PMPro (post, page, shortcode, or block) to offer members-only events wit Timely All-in-One Events Calendar.

I've made a change (and point release coming out) to only load on older versions instead. There's no way to rollback their plugin to pre 3.0

I'm leaning towards updating "We integrate with All-in-One Events Calendar" from our docs/readmes to just point to our restrict content section.
