QTextMarkdownImporter: spell CRLF literal correctly

Amends eced22d

tst_QTextMarkdownImporter::frontMatter(yaml + markdown with CRLFs)
now does explicit replacement of LF with CRLF: git may convert the file,
so we can't rely on the CI test system checking out a true copy of
yaml-crlf.md; but QFile::open(ReadOnly | Text) ensures that we will
have LF line endings, not CRLF.
