[tldoc] tl24 one more time

This time it's really really final? Maybe :)? Diff below. -k

 Add a \texttt{.bat} extension to the invocations if the same directory
 also contains \texttt{install-tl-windows.exe}. This will not
 normally be the case, unless you've mirrored the \dirname{tlnet} directory
 locally.
 
+Non-ASCII characters in the path for the \TL\ installation must be
+avoided.  This may be a problem particularly under Windows 11, where
+users are forced to use a Microsoft network account.  See
+\url{https://tug.org/texlive/windows.html\#nonascii} for some
+workarounds.
