Subject: Keep interactive uses of 'recenter' backward compatible (Bug#31325)

* window.c (Frecenter): Change the interactive spec to always pass
a non-nil value to the REDISPLAY argument when called interactively.
* window.el (recenter-top-bottom): Make sure 'recenter's second
argument is non-nil everywhere.
* windows.texi (Textual Scrolling): Update documentation of
'recenter'.
