runtime(htmldjango): Add syntax highlighting of comparison operators

The presence `djangoOperators` in the file `syntax/django.vim` and
having the highlight function with a `match` statement leads to a
highlight spill-over with other elements defined in `syntax/html.vim`.
To avoid the highlight spill-over declare a region called
`djangoTagBlockNaive` to limit `djangoOperator` to only be matched
within.
