Allow more granular control over syntax highlighting

[Nikita0x]

I want to be able to customize my syntax highlighting a lot.
For instance, it is easier for me to read types with generics, when typed parameter is highlighted as function parameters - I see them to be very similar.
Yet in zed typed parameter is highlighted as an overall type.
I cannot highlight in zed - interfaces and types with different colors, I cannot highlight true and false with different colors, I cannot highlight different operators (for instance ... operator) differently - because they are all operators in Zed...

I checked the highlights.scm - some operators are swiped under the keywords category - which is incorrect.
And most importantly - as I understood - the parser just does not assign any names to those tokens so I cannot even differentiate them (for instance with booleans. Why we are only limited to @boolean and not @boolean.false, @boolean.true. I am a visual, I want to see my true as green, and false as red.

Unfortunately, I am not that experienced to rewrite or write additions to parser and especially scheme language, I just want to throw it out there that I and, more users - would prefer more granularity in syntax customization.
