We need to use an `h_stack` here to get the icon and the label to
position themselves next to each other instead of one on top of the
other.

This ensures blocks get mouse events before the editor beneath
them.

This prevents dispatching actions on buttons that were not the target of the click.

This PR fixes an issues where the toolbar would not appear for the
center pane when Zed2 initially loads.

We resolved this by adding a call to initialize the center pane when the
workspace is initialized

Due to changes in the way subscriptions work we can on longer observe an
event that is emitted in the same event cycle in which the subscription
is created.

Because of this we need to explicitly initialize the center pane, as it
won't get performed by the subscription.

For a brief period on this branch, we were taking a `DispatchTree`. Doing so
resulted in more accurate key bindings but it meant that we would have had to
recompute the app menus every time the key context changed.

We decided to err on the side of keeping things simple and work in the same
way they worked back in zed1.

`HighlightedLabel` was not respected as the default color for
non-highlighted text.

Add hidden_action_types to CommandPaletteFilter.
WindowContext.available_actions now returns global actions as well.

Added an ephemeral root node so that even if there's no window/focused handle we still have something to dispatch to.

(in the first commit, this PR autoformats both yaml files with Zed's
default prettier, to be able to edit those in prettier from now on)

Bundling is a relatively long procedure, and now we have nightly builds
for zed2 (with their own lifecycle, CI file and tag for triggering it
from non-main branch).

Hence, bundling zed1 and/or zed2 by default looks wasteful and
unnecessary, disable them by default.
There's still a `run-build-dmg` label that enables bundling for any PR
needed, and a `startsWith(github.ref, 'refs/tags/v')` check in the CI
run to keep the releases working.
