This PR removes the loading of the Vim keymap temporarily.

This cuts down on the noise from all of the Vim-related action warnings.

We can resume loading the Vim keymap once we're ready to add Vim
support.

For any push (or force-push) into a branch, a separate CI workflow is
run.
This is rather worker-consuming, esp. given the fact that GitHub will
wait for the last job to update PR's status.
So cancel every old job for the same branch if it's not `main`.
CI run on `main` might catch a regression brought in by specific PR
merged, so run CI on every commit due to that.

Current panic reports are now harder to tell apart by the following
criteria:
* nightly or preview or stable
* zed2 or zed1

Current PR adds uses a different version for zed2 (2.0.0, selected
relatively arbitrary as zed2 is nothing officially released now) and
adds a `-nightly` suffix to the version number of the nightly bundle.

Now inlays are visible in all zed2 themes, but 
* always have a blue color which is the same as some theme colors
* not other hint-related style changes like font width, background, etc.
seem to exist in the theme, ergo not propagated.

In general though, people want those style changes applied to their
hints, so we might want to do something about it later.
I've left a `// todo!("what about the rest of the highlight style parts
for inlays and suggestions?")` in the corresponding places for that.

Nothing earth-shattering here, but all our geometry types are now fully
documented.

other.
