test(qa): rewrite the Linux LibreOffice fidelity baseline from the CI runs of #897 and #899

[DemchaAV]

Why

Both of these were merged with their Word and Windows LibreOffice baselines rewritten, and their Linux LibreOffice baseline left to follow from their CI runs:

• fix(docx): settle a list item's exact lines with the page, and what a cell's lines carry at its end #897 settles a list item's exact lines with the page, and what a cell's lines carry at its end.
• fix(docx): give a paragraph opening a row's column the gap above its first line out of the space above the row #899 gives a paragraph opening a row's column the gap above its first line out of the space above the row.

Until then the Linux baseline holds the documents they move as they stood before, so a change that undid either would pass the DOCX fidelity job on Linux.

What changed

libreoffice-linux.tsv and libreoffice-linux-lines.tsv now match the docx-fidelity artifact of #899's last CI run (38571103664) byte for byte, summary and lines. That run measured 2.5-dev with #897 merged, and its first run (38564227066) measured the same.

#897: the rows of the 40 documents it moves on Linux. All of them are among the 48 whose DOCX it changes. They are taken from the artifact of #897's last CI run (38551609338), which its first run (38550387636) measured byte for byte.

• Lines that moved by more than 0.05pt: 625 nearer the page, 303 further from it.

• Medians of the 38 documents whose summary row changes: 17 nearer, 17 further, 4 the same. Their sum falls by 0.24pt.

  Document	Median before	Median after
  cv-panel	0.34pt (p90 0.71pt)	0.21pt (p90 0.33pt)
  cv-terracotta_rail	0.25pt	0.17pt
  cv-serif_headline	0.26pt	0.19pt
  invoice-consulting	0.14pt	0.08pt
  letter-panel	0.13pt	0.04pt
  invoice-obsidian	0.27pt	0.37pt
  cv-violet_grid	0.22pt	0.27pt

• Further documents. invoice-obsidian and cv-violet_grid stand further from the page here, as they do in Word and Windows LibreOffice. Their lines already stood high, and the settled tenth of a point moves them a step further.

• Lines past 2pt. invoice-merchant's go from 12 to 5, and it passes. invoice-payments' go from 45 to 40.

• Acceptance goes from 52 to 53 of 62 documents.

#899: the rows of the five documents it moves. These are cv-orange_ops, cv-serif_headline, invoice-workspace, proposal-editorial and proposal-northline, the same five whose DOCX it changes.

• Lines that moved by more than 0.05pt: 46 nearer the page, 2 further. The two further are lines of cv-orange_ops, each by 0.05pt.

• 90th percentiles:

  Document	Before	After
  proposal-editorial	0.65pt	0.35pt
  proposal-northline	0.48pt	0.42pt
  cv-serif_headline	0.65pt	0.59pt

  proposal-northline's median goes from 0.17 to 0.13pt.

• Acceptance stays at 53 of 62.

Verification

• ./mvnw -B -ntp test -f qa/pom.xml → BUILD SUCCESS, 1820 tests.
• This PR's DOCX Fidelity (LibreOffice) job holds 2.5-dev's export to the new baseline.
