Build fails for editor-ubuntu-2023.1.0f1-webgl-1.1.2 with URP

[JohannesDeml]

Bug description When building the project (Link) with Unity 2023.1.0f1 with urp (Branch) I get the following error:

emcc: error: '/opt/unity/Editor/Data/PlaybackEngines/WebGLSupport/BuildTools/Emscripten/llvm/wasm-ld @/tmp/emscripten_v1u3qz8c.rsp.utf-8' failed (received SIGKILL (-9))

The build works in CI when creating a development build, but not for normal builds (for both WebGL1 & 2). When building locally on a windows machine I don't have any errors, also when using the commandline to start the build the same way as in the action.

How to reproduce

1. Fork https://github.com/JohannesDeml/UnityWebGL-LoadingTest
2. Run action to get a unity license and set it in the secrets
3. Push the tag 2023.1.0f1-urp-webgl2 to the 2023.1-urp branch
4. A new build should be triggered by automation, this build will fail

Expected behavior

The build should finish successfully
