runtime(filetype): update htmldjango detection

- update tags to detect djangohtml based on
https://docs.djangoproject.com/en/5.0/ref/templates/builtins/#built-in-tag-reference

- increase the lines to inspect to 40 lines

10 lines is too few and might result in high false negative.
Increasing it to 40 lines should reduce the false negative.

closes: #15037
