Previously I've wanted to have this page spell out the concrete version number that our clients support, rather than the policy we use for determining that version number, because that's the sort of question that I feel like as a user I'd want a straight answer to and would be annoyed if I couldn't get one. But as the text stands, it's come to look more like it's the policy (something that's heavyweight to change) than like the value that the policy currently happens to work out to. Also, because this page is kind of chaotically organized (and fixing that is a bigger yak than I want to shave right now), it repeats the 18-month rule in three separate places and the current value (version 4.0) is in a fourth separate place, so it looks internally inconsistent. Let's therefore take a different tack: like in those other three spots on this page, state just the policy instead of the value it currently works out to; but also add a link to help the reader pin down for themselves what value that does work out to. This also means we no longer need to update this page as old releases age and that value advances. Also fix a typo, and cut the reference to working degraded on older releases. Starting earlier this year we finally started hard-refusing such connections: https://github.com/zulip/zulip-mobile/issues/5102 https://github.com/zulip/zulip-mobile/pull/5633 (which was because there were some swathes of compatibility code that we could only cut if we completely broke the handling of ancient servers, and so we preferred to have the app communicate that break clearly up front.)
