Subject: [PATCH] docs: Fix tab-switcher keybindings (#65105)

## Summary

Fixes missing keybinding pills in the Tab Switcher documentation on
Linux.

The keybinding processing in `docs/theme/plugins.js` assumed every
`<kbd>` element contained both macOS and Linux variants separated by
`|`. Hand-written keybindings such as `ctrl`, `tab`, and `shift` only
contain a single value, making them render empty on Linux.

This change falls back to the first keybinding when a Linux-specific
value is not provided.

Also removes the `tab_switcher::ToggleAll` keybinding reference from the
documentation, since the action does not have a default keybinding.

Closes #65087.

## Testing

- Ran the Zed documentation locally with `mdbook serve docs`.
- Verified the Tab Switcher documentation on Linux.
- Confirmed that single-sided keybindings (`ctrl`, `tab`, `shift`, etc.)
now render correctly.
- Confirmed that keybindings containing both macOS/Linux variants
continue to render correctly.
- Confirmed the `ToggleAll` entry no longer displays the 'no default
binding' message.

## Self-review

performance.

[checklist](https://zed.dev/docs/development/ui-checklist).
