Fix inspector_dock.rst - Show inspector menu route was wrong

When you follow the "Editor > Editor Settings" route an Editor Settings panel opens - without any Editor Docks sub-panel.

This had me stumped at first while following the documentation.

A menu path that actually triggers the Show Inspector function is:
"Editor > Editor Docks > Inspector"

I propose updating the menu path for clarity.
