fix(editable-layers): Fix import of PathMarkerLayer

[zbigg]

Summary:

• fix invalid cross-module import in @deck.gl-community/editable-layers

---

Fixes, fegression from #333

This fix interesting issue with tsc jumping from "{moduleA}/dist/..." to "{moduleB}/src" when checking types.

Note, that currently distributed node_modules/@deck.gl-community/editable-layers/dist/lib/layers/segments-layer.d.ts for reads like this:

import { PathMarkerLayer } from "../../../../layers/src/path-marker-layer/path-marker-layer.js";

That means, it imports not from "official types" of @deck.gl-community/layers which live in dist/..., but does "self-path-traversal-attack" and reaches to 'src' folder of this package.

Thanks for testing and fixing!
This may have been done when asking LLM to move the layers.
We may want to add some cross-import rules to AGENTS.md
