Earlier, the `s` hotkey just narrowed to the stream of the selected
message (to a topic), while `shift+s` narrowed to the conversation view
(topic / dm) of the selected message.
Now, the `shift+s` hotkey has been removed (but retained for toggling
subscription to a stream when the stream overlay is active), and the `s`
hotkey takes on double duty: if the current view is not topic / dm, it
narrows to that, else when in topic view, it switches to stream view. It
has no effect when in dm view. Documentation has been updated for this
both in the help center, and the in-app `Keyboard shortcuts` menu.
A deprecation notice has been added for `shift+s` as well.
Fixes: #24226.
A new hotkey, lowercase `z` (for `zoom`) has been implemented to allow
the user to go to the near view of the selected message with 1 keypress.
Documentation has been added for this both in the help center, and the
in-app `Keyboard shortcuts` menu.
The effect is identical to clicking on a message's timestamp, which
links to that message's near view.
Fixes: #24227.
These files are not Jinja2 templates, so there's no reason that they needed
to be inside `templates/zerver`. Moving them to the top level reflects their
importance and also makes it feel nicer to work on editing the help center content,
without it being unnecessary buried deep in the codebase.
