    [Ada] Adjust description of Pure_Function pragma
    
    The current wording can be read as implying that the result of a call
    to a pure function does not depend on the context, which is incorrect.
    The pragma only guarantees the absence of side effects of such a call.

            * doc/gnat_rm/implementation_defined_pragmas.rst (Pure_Function):
            Fix ambiguous wording about context dependence.
            * gnat_rm.texi: Regenerate.
