Use a suggestion instead of a fixer, because this can break type checks.

The resulting type of the nullish coalesce is only influenced by the right operand if the left operand can be `null` or `undefined`.
|
| 50 |
+
After removing the non-null assertion the type of the left operand might contain `null` or `undefined` and then the type of the right operand
|
| 51 |
+
might change the resulting type of the nullish coalesce.

|
| 53 |
+
|
| 54 |

function test(x?: string): string {

const bar = x! ?? false; // type analysis reports `bar` has type `string`
