Suffixed events not showing up on city landing pages

[iandunn]

1. Create 2 events locally, one at https://events.wordpress.test/rome/training/ and another at https://events.wordpress.test/rome/training-2/
2. Visit https://events.wordpress.test/rome/ and you should see both. You may need to run the events_landing_prime_query_cache cron if you don't see them.
3. Visit https://events.wordpress.test/rome/training/. The page shows /training/, but not /training-2/

I think this cause might be this regex:

wordcamp.org/public_html/wp-content/themes/wporg-events-2023/inc/event-getters.php

Line 256 in 923023f

$regex = "^/$city/\d{4}/$title/";

It should maybe be something like ^/$city/\d{4}/$title[-\d]*/ instead, so that the -2 is allowed but not required.
