Fix two side window problems noted by Alex (Bug#27999)

* lisp/window.el (display-buffer-in-side-window): Fix doc-string
typo.
(delete-other-windows): Rename the `no-delete-other-window'
parameter to `no-delete-other-windows' (see the discussion in
Bug#27999 for the rationale of this change).
* doc/lispref/windows.texi (Deleting Windows)
(Frame Layouts with Side Windows, Window Parameters): Rename
`no-delete-other-window' to `no-delete-other-windows'.
