Closes #41580

This implements Helix's jump list, Zed already supports jumplists, so
all that is done is re-binding ctrl-s to to that instead. In another PR
we can extend this by adding space+j functionility to see all selections
in jumplist.

after this change:
Pressing Ctrl+S saves the current cursor position to the jumplist,
allowing the user to navigate back to this position using Ctrl+O
(backward) and Ctrl+I (forward), consistent with regular Helix's
behavior.
