runtime(vim): Update base-syntax, allow whitespace before :substitute pattern

Allow whitespace between the :substitute command and its pattern
argument.  Although unusual, it is supported and there are examples in
the wild.

Match Vi compatible :substitute commands like :s\/{string}/.  See :help
E1270.

closes: #14923
