This reduces LLVM IR size of editor (that's one of the heaviest crates
to build) by almost 5%.

LLVM IR size of `editor` before this PR: 3280386
LLVM IR size with `editor::edit` changed: 3227092
LLVM IR size with `editor::edit` and `language::edit` changed: 3146807

Release Notes:
- N/A

One of our users ran into an issue where typing "true quote" characters
(option-[ for „ and option-] for ‚) was not possible; I've narrowed it
down to a collision with Copilot's NextSuggestion and PreviousSuggestion
action default keybinds. I explicitly did not want to alter the key
bindings, so I've went with a more neutral fix - one that propagates the
keystroke if there's no Copilot action to be taken (user is not using
Copilot etc). Note however that typing true quotes while using a Copilot
is still not possible, as for that we'd have to change a keybind.

Fixes zed-industries/community#2072


Release Notes:
- Fixed Copilot's "Suggest next" and "Suggest previous" actions
colliding with true quotes key bindings (`option-[` and `option-]`). The
keystrokes are now propagated if there's no Copilot action to be taken
at cursor's position.

Release Notes:

- Added documentation display for autocomplete items.
- Fixed autocomplete filtering blocking the Zed UI, causing hitches and
input delays with large completion lists.
- Fixed hover popup link not firing if the mouse moved a slight amount
while clicking.
- Added support for absolute path file links in hover popup and
autocomplete docs.

Release Notes:

- Added Vue language support.
