Status filters exclude extensions with multiple statuses

[holly-cummins]

See, for example, https://quarkus.io/extensions/?status=stable%2Cexperimental%2Cpreview%2Cdeprecated. It should show all extensions and it shows ~640.

||
      // (Array.isArray(statusFilter) && statusFilter.some(r => extension.metadata.status && extension.metadata.status.includes(r)))

in filters.js may fix this, but it will want unit tests, too.

We should also have unit tests for extensions with null statuses.
