Fix sha256 sum for git-lfs script

Reference Issues or PRs

Fixes #159

I have skimmed over the script to make sure its coming from official sources:
https://packagecloud.io/github/git-lfs/packages/ubuntu/focal/git-lfs_3.5.1_amd64.deb?distro_version_id=210

Ideally we should download the .deb from above link and then verify the checksum given in the above link, but that's probably for another time. This is to unblock us from updating images.

Documentation

Access-centered content checklist

Text styling

• The content is written with plain language (where relevant).
• If there are headers, they use the proper header tags (with only one level-one header: H1 or # in markdown).
• All links describe where they link to (for example, check the Nebari website).
• This content adheres to the Nebari style guides.

Non-text content

• All content is represented as text (for example, images need alt text, and videos need captions or descriptive transcripts).
• If there are emojis, there are not more than three in a row.
• Don't use flashing GIFs or videos.
• If the content were to be read as plain text, it still makes sense, and no information is missing.

Any other comments?

When I download locally see the new checksum (8c4d07257b8fb6d612b6085f68ad33c34567b00d0e4b29ed784b2a85380f727b).

I was able to find 5fc673f9a72b94c011b13eb5caedc3aa4541b5c5506b95d013cb7ba0f1cf66cf from wayback machine and the diff appears to be literally one extra empty line at line 196 (opening the current file and removing that line restores the old hash).
