bug#38928: bad docstrings for image-dired rotate commands

[Christophe Deleuze]

* bug description

The docstrings for commands image-dired-rotate-thumbnail-left and
image-dired-rotate-thumbnail-right say that:

"The result of the rotation is displayed in the image display area
and a confirmation is needed before the original image files is
overwritten.  This confirmation can be turned off using
`image-dired-rotate-original-ask-before-overwrite'."

This is not the case, thumbnail rotation is performed immediately (and
rightly so, as the thumbnail has been generated by image-dired and does
not need such caution).

On the contrary, such a display of rotation result and ask of
confirmation is performed by commands image-dired-rotate-original-left
and image-dired-rotate-original-right that rotate the *original*
pictures.  But this is not mentionned in their docstrings.

* fix description

The above mentionned text should be moved from the docstrings of
image-dired-rotate-thumbnail-left/right to those of
image-dired-rotate-original-left/right.  This is a very simple
modification, affecting only the docstrings.
