test(qa): rewrite the Linux LibreOffice fidelity baseline for the table text cell seat

[DemchaAV]

Why

The DOCX Fidelity (LibreOffice) job holds every line of the corpus to libreoffice-linux*.tsv.
#876 moved a table's text cells onto the page's baselines and rewrote the Word and Windows
LibreOffice baselines with it, but the Linux one still records the export before it: a later
change that set those tables back off the page by as much as #876 brought them on would pass
the job.

What changed

qa/src/test/resources/docx-fidelity/libreoffice-linux.tsv and libreoffice-linux-lines.tsv
are the measured files from the job's artifact on #876's last head (run 38132116069, the tree
that was merged as 8fa0340), unedited:

• 9 documents nearer, the sum of the medians 1.03pt nearer — invoice-consulting_long
  0.69 → 0.22pt, invoice-consulting 0.65 → 0.18pt, invoice-classic_long 0.17 → 0.08pt,
  invoice-subscription 0.42 → 0.34pt.
• 5 further, by 0.05 to 0.06pt — invoice-merchant (one line more past 2pt),
  invoice-metered, proposal-modern, cv-editorial_blue, invoice-modern — the documents
  fix(docx): stand a table's text cells on the page's baselines, through their row's margins #876 names: Linux's face substitutions already set the first three 0.7 to 10pt off, and the
  last two are the table set low in its cells and the column LibreOffice sets high.
• 45 unchanged; no document gains or loses a page.

Verification

The files are the job's own measurement, so the job passes against them on this branch's run;
git diff touches only the documents listed above.
