runtime(vim): Update base-syntax, revert last change to vimUserFunc (#14202)
Fix highlighting of ":echo (expr)" (broken in commit 61887b3) by
re-enabling the original fix for #9987.
Addresses https://github.com/vim/vim/pull/14199#issuecomment-1999732062.
This will be fixed more generally when there is context-sensitive
matching for commands and functions.
