Pull Request Overview

This PR modifies the documentation build workflow to debug a failing checkout issue in GitHub Actions by enabling recursive submodule cloning and LFS (Large File Support) for all documentation builds instead of only for PyTorch-specific builds.

• Enables recursive submodules and LFS for all package builds (fabric and pytorch) instead of conditionally enabling them only for pytorch
• Simplifies the checkout configuration by removing conditional logic

Seems the recursive is fine now, so we can reopen it if needed... 🦩

@Borda problem is still present...is this not a fix?

Yeah, I saw it, but then I observed that it happened also with this PR, so probably I did not find the fix... :(
