feat(infobox): do not show accomodation button based on exception list

[hjpalpha]

so far only as an idea for discussion on admin discord

Summary

add exception list support for the accomodation button

• json in mediawiki namespace and hence can only be edited by admins (to avoid misusage)
• supresses the display for these cases
• reason: events could not allow crowds, imo we should have an option to not display the button for those

How did you test this change?

dev

Could we not just have a default empty json list on commons to avoid the Page.exists('MediaWiki:AccomodationExclusionList.json') or does mw.loadJsonData not support commons?

yeah sadly can't load the json from commons

reason why i didn't use a data module is that we would have to lock down the page on each wiki (against editing/creating)

Anything blocking this?
