* bug#63810: 29.0.91; typescript-ts-mode grammar missing the "is" keyword

Reproduction:

1. C-x C-f test.ts
2. Insert
   ```typescript
   function isFish(pet: Fish | Bird): pet is Fish {
     return (pet as Fish).swim !== undefined;
   }
   ```
3. Observe the `is` keyword isn't highlighted.

Expectation:

TypeScript has a concept called type predicates, which introduces a
keyword called `is`.
