startup: do "syntax enable" instead of "syntax on"

Browse Source 
"syntax on" overwrites existing highlight groups, while "syntax enable"
just sets missing groups. This change prevents user defined highlights in
init.vim/lua to get overwritten. The manual recommends "syntax enable" for
new configurations anyway, "on" command was probably used as it is the
implicit default.
