Ran a cleanup of ~24k file entities from the domain
`page-one.live.cf.public.springer.com`, which are not entire journal articles
but just "samples" (one or two pages).

See `file_single_page` cleanup notes for prep and background.

Start small:

    zcat /srv/fatcat/datasets/files_pageone.json.gz \
        | jq '"file_" + .ident' -r \
        | head -n50 \
        | parallel -j1 fatcat-cli get {} --json \
        | jq . -c \
        | rg -v '"content_scope"' \
        | rg 'page-one.live.cf.public.springer.com' \
        | pv -l \
        | fatcat-cli batch update file release_ids= content_scope=sample --description 'Un-link and mark Springer "page-one" preview PDF files as content_scope=sample'
    # editgroup_hcumfatcvjg3fheycnm2uay5aq

Looks good, accepted that editgroup.

Run entire batch, in auto-accept mode:

    zcat /srv/fatcat/datasets/files_pageone.json.gz \
        | jq '"file_" + .ident' -r \
        | parallel -j1 fatcat-cli get {} --json \
        | jq . -c \
        | rg -v '"content_scope"' \
        | rg 'page-one.live.cf.public.springer.com' \
        | pv -l \
        | fatcat-cli batch update file release_ids= content_scope=sample --description 'Un-link and mark Springer "page-one" preview PDF files as content_scope=sample' --auto-accept
