git svn: remove deprecation note (since it is no longer included in Git for Windows, anyway) (#6142)

As of git-for-windows/MINGW-packages#187, Git
for Windows no longer includes `git svn` in its installers and portable
Git editions.

As a consequence, the deprecation note is no longer necessary.

Even worse: Since the recommendation for users who want (or at least
need) to continue using `git svn` is to use the MSYS2 package instead,
and that MSYS2 package is built from Git for Windows' source code, they
would now be bothered by a note that they do not need.

So let's drop that deprecation note.
