Temporarily revert #16700 to deal with this error:
`error: manifest path `../crates/docs_preprocessor/Cargo.toml` does not
exist` as it was causing the docs-preprocessor not to run, meaning
unexpanded templates were showing up in the public docs.
Reverts zed-industries/zed#16700
Release Notes:
- N/A
This PR adds a mdbook preprocessor for supporting Zed's docs.
This initial version adds the following custom commands:
**Keybinding**
`{#kb prefix::action_name}` (e.g. `{#kb zed::OpenSettings}`)
Outputs a keybinding template like `<kbd
class="keybinding">{macos_keybinding}|{linux_keybinding}</kbd>`. This
template is processed on the client side through `mdbook` to show the
correct keybinding for the user's platform.
**Action**
`{#action prefix::action_name}` (e.g. `{#action zed::OpenSettings}`)
For now, simply outputs the action name in a readable manner. (e.g.
zed::OpenSettings -> zed: open settings)
In the future we'll add additional modes for this template, like create
a standard way to render `{action} ({keybinding})`.
## Example Usage
```
To open the assistant panel, toggle the right dock by using the {#action workspace::ToggleRightDock} action in the command palette or by using the
{#kb workspace::ToggleRightDock} shortcut.
```
Release Notes:
- N/A
To ease navigating on pages that are long and having a birds-eye view of
all the available content.
This is done client-side and done via the files initially generated by
the `mdbook-pagetoc` plugin ([crates.io link
here](https://crates.io/crates/mdbook-pagetoc)).
