Enable include_lfs_blobs_in_archive feature flag by default

Merged Stan Hu requested to merge sh-default-enable-include-lfs-blobs into master

This has been enabled on GitLab.com for over a week. There were hundreds of thousands of /internal/lfs of API calls made from the new Gitaly LFS smudge filter with no apparent errors. Project archives are cached via a CDN on GitLab.com, and for self-managed hosts Workhorse also has a local disk cache, so that mitigates any extra network traffic generated by larger archives.

https://log.gprd.gitlab.net/goto/97ba3b8c821c13c97929532bdcee1920 shows:


There were a few thousand 404 errors, but a spot check shows those LFS pointers did not exist as entries in LfsObject.
