Repro Code

// failsconsttest1:(someCondition:boolean)=>void=someCondition=>{if(someCondition===true){}};// should failconsttest2:<Textendsboolean>(someCondition:T)=>void=someCondition=>{if(someCondition===true){}};

ESLint Config

module.exports={parser:"@typescript-eslint/parser",rules:{"@typescript-eslint/no-unnecessary-boolean-literal-compare":"error"},};

tsconfig

{"compilerOptions": {"strictNullChecks":true  }}

Expected Result

I expect all use-cases to be consistent and report as errors.

Actual Result

The use-cases with a type constraint doesn't report as an error (even though it should).

Additional Info

This seems similar to#10311, and it looks like the fix should be similar.

Note that this issue is also similar to#10442, and I wasn't sure if I should create one issue for each rule or aggregate them under a single issue. I apologize if this was a bit spammy. I checked existing rules for similar problems after resolving#10311.
