This conflict is not documented in `CONFLICTS.md` anymore, was brought back in this commit:
f80f42d

However according laminas/laminas-code#67 and considering:
https://github.com/Sylius/Sylius/blob/49b070933b32761de08475fafd6d86dca10d40ff/.github/workflows/application.yml#L104 should no longer be an issue.

If it still is, then I guess the build will show it and there should be a new issue opened somewhere.
