workflows: Enable lfs in gh-pages

Sometimes the logs can be large.
For example:
  remote: error: File 224/data/attachments/305b606753ef6ea8.zip is 213.16 MB;
this exceeds GitHub's file size limit of 100.00 MB
  remote: error: GH001: Large files detected. You may want to try
Git Large File Storage - https://git-lfs.github.com.

This will help save the report and analyze it.
