Test discovery in `class`es fails unless all fields contain doctest

[Iron-E]

Hello! Thank you for this plugin. I sorely missed doctests, coming from Rust.

Here is a minimum example of the issue:

class Foo {
    public constructor() { }

    /** some note about this property */ // ← this causes the test discovery to fail
    private readonly bar: number = 3;

    /**
     * @import.meta.vitest
     * ```ts
     * assert(false);
     * ```
     */
    public readonly baz = (): void => { }
}
