Utilities/Release: Install docs in unversioned directory (#15692)

Our upstream-built release tarballs already contain many unversioned
paths and so will never overlap with another version of CMake in the
same installation prefix.  Therefore we do not need a versioned name for
the documentation directory.  Configure our release binaries to place
the documentation in an unversioned directory so that one can use the
same path to refer to the documentation locally even after updating
CMake.  For example, on OS X one may see the documentation in
`/Applications/CMake.app/Contents/doc/cmake/html/index.html`.
