overlookmotel c966acaac5 fix(parser): do not omit < token opening type argument list (#26328 )

Fix tokens produced when `<<` opens a type argument list. e.g.:

```typescript
type Bar = ReturnType<<T>(x: T) => number>;
```

Previously only 1 `<` token was produced between `ReturnType` and `T`. This PR corrects that so 2 `<` tokens are produced.

TS-ESLint get this wrong too - hence why this wasn't noticed before, as our conformance tests compare to TS-ESLint.

PR submitted to fix TS-ESLint: https://github.com/typescript-eslint/typescript-eslint/pull/12821

In meantime, this PR skips the erroneously failing ESTree tokens conformance tests. We can can re-enable those tests once the fix lands in TS-ESLint.
