Do not collapse multiple terms on the download page

[davewhiteland]

Problem

On the download page we currently collapse the terms if there are "too many" and only display a few (3), with a toggley button.

Remove this feature: don't hide any terms. It was really only introduced because that page was getting too big: but the reason the page was getting too big was largely because it was (for bicameral parliaments) showing two houses.

Proposal

Stop doing it. Show all the terms. Be proud of the number of terms.

Incidentally, doing this makes #14427 much more useful and sensible.

Acceptance Criteria

User visits page, user sees all terms available. No collapsing, no JavaScript, no button.

Not Required

Prerequisites

Not necessary but maybe best once #13599 is in place, since it's happening in there.

Related issues

See #14427 which makes more sense when there are many terms.

Design?

No. Just killing the silly JavaScript that @davewhiteland added to make it all happen in the first place.
