Bug: only one live register showing in the summary box at the top of country pages

[StephenAbbott]

Countries like the UK, Nigeria and Slovakia have multiple live beneficial ownership registers listed in the implementation details section of their country pages on the Open Ownership website:
https://www.openownership.org/en/map/country/united-kingdom-of-great-britain-and-northern-ireland/
https://www.openownership.org/en/map/country/nigeria/
https://www.openownership.org/en/map/country/slovak-republic/

But since our recent tweaking of the Notion integration for country pages - see #432 - only one of these live registers is showing in the white summary box near the top of the country pages.

Could this be fixed to show multiple live register names and links? Or do we need to re-examine how to display the full list of live registers for any country/jurisdiction on these pages?
