list/map variable type syntax highlighting

[frittsy]

While I know the list and map functions were officially removed in v0.15.0, they are still valid types for variables and should not be highlighted as red, as shown below. I believe this was broken in #604.

I can take a stab at fixing this, but not sure if it would be better to simply add these as additional types to terraform_type_keywords, or if there needs to be something more akin to structural_types but for all the collection types.

Thanks for the report. I'm able to reproduce this behavior.

list() is always highlighted as invalid.deprecated.terraform even if it's a valid type in variable blocks.

The red color should only be applied in a function-call context.
