docs: Introduce command palette earlier (#14467)

Buzz and Thorsten Ball created 

Can't get to many of the settings on linux without opening it, and can't
know the default keystroke to get to it without knowing where to look
first, so its a chicken-n-egg problem of needing to use a
default-keystroke to set the key bindings, esp on linux.

+## Command Palette
+
+The Command Palette is the main way to access functionality in Zed, and its keybinding is the first one you should make yourself familiar with.
+
+On macOS, use `⌘-P` (`cmd-shift-p`) to open the Command Palette.
+
+On Linux, use `⌃-P` (`ctrl-shift-p`) to open the Command Palette.
+
+The Command Palette allows you to access pretty much any functionality that's available in Zed.

+
+Try it! Open the Command Palette and type in `new file`. You should see the list of commands being filtered down to `workspace: new file`. Hit return and you end up with a new buffer!
+
+Any time you see instructions that include commands of the form `zed: ...`  or `editor: ...`  and so on that means you need to execute them in the Command Palette.
