Memory exhaust 1024M in queued export with FromQuery method

[sebestenyb]

1️⃣ Why should it be added? What are the benefits of this change?

Please refer ticket #2209

In order to use LazyCollection in a FromCollection export, we need to expand the return type of the QueuedWriter class. Since we can't use union types due the support of older PHP version, we need to remove the return type, and do it via doc blocks again.

2️⃣ Does it contain multiple, unrelated changes? Please separate the PRs out.

No

3️⃣ Does it include tests, if possible?

No

4️⃣ Any drawbacks? Possible breaking changes?

No

5️⃣ Mark the following tasks as done:

• Checked the codebase to ensure that your feature doesn't already exist.
• Take note of the contributing guidelines.
• Checked the pull requests to ensure that another person hasn't already submitted a fix.
• Added tests to ensure against regression.

6️⃣ Thanks for contributing! 🙌

We should be able to add a test for this, no? If we would add a test right now with using a lazycollection the test would fail on a type error, right? After this PR that test should succeed. Would then prevent regressions of this breaking again in the future.

I've added a test, which fails if I restore the original QueuedWriter, and it runs correctly locally, but it fails in GH Actions for some reason.

I'll have a look at GH actions
