perldeprecation: Clean up text about grapheme delims
This changes the text to make more sense in light of the fact that the
the deprecation has changed to illegality.

@@ -230,25 +230,21 @@ A grapheme is what appears to a native-speaker of a
language to be a
character. In Unicode (and hence Perl) a grapheme may actually be
several adjacent characters that together form a complete grapheme. For
example, there can be a base character, like "R" and an accent, like a
-circumflex "^", that appear when displayed to be a single character with
-the circumflex hovering over the "R". Perl currently allows things like
-that circumflex to be delimiters of strings, patterns, I<etc>. When
-displayed, the circumflex would look like it belongs to the character
-just to the left of it. In order to move the language to be able to
-accept graphemes as delimiters, we have to deprecate the use of
-delimiters which aren't graphemes by themselves. Also, a delimiter must
-already be assigned (or known to be never going to be assigned) to try
-to future-proof code, for otherwise code that works today would fail to
-compile if the currently unassigned delimiter ends up being something
-that isn't a stand-alone grapheme. Because Unicode is never going to
-assign
-L<non-character code points|perlunicode/Noncharacter code points>, nor
-L<code points that are above the legal Unicode maximum|
-perlunicode/Beyond Unicode code points>, those can be delimiters, and
-their use won't raise this warning.
-
-As of Perl 5.30, delimiters which are unassigned code points, or which
-are non-standalone graphemes are fatal.
