Feature request: Make ghcup list --hide-old (-o) the default

[mpilgrem]

For ghcup tui, not showing old versions is the default and key 'a' toggles between the default and showing old versions also.

Currently ghcup list shows old versions also, and --hide-old (-o, for short) is passed to filter out all old versions (not just GHC old versions, as stated by in-app help).

As ghcup list grows in length, I suggest that --hide-old is the sensible default, with a flag for --no-hide-old.

That would be a breaking change. People are using ghcup list in scripts (github runners even used to). So any changes to that could cause large breakage. Sure, we could have a different default when --raw-format is passed, but that would complicate the interface (and you can still sed/grep even without it).

It is a minor thing now ghcup tui supports Windows. In my case, 'muscle memory' means that I still command ghcup list in error (as what I need to avoid the 'noise' of old versions is ghcup list -o or ghcup tui).

Is there a reason why the output of ghcup list does not reveal the Old tag - it does not distinguish 'Old' from 'other non-Latest'?

Since it's kind of an arbitrary selection, I'm not sure having that information permanently visible is useful.

Regarding the output length: we could drop into the pager when the output exceeds terminal height (or is used as part of a pipe... it's possible to detect that programmatically... git does that too).
