highlights: create subscoping for ternary operator

After https://github.com/nvim-treesitter/nvim-treesitter/issues/470,
we decided to use `@conditional` for ternary operator instead of
operator despite `@conditional` is documented for keywords only.
A sub-scoping can make it easier for people to highlight this operator
group differently.

Also unify the usage of `@conditional...` across languages.
