Subject: [PATCH] Adapt tests to fewer bogus font ascent/descent value
 warnings.

Since MuPDF commit 3d89b00ae59c6ed1f042d77e049a5668b32ca4ca
"Only warn about non-zero bad ascender/descender font values"
MuPDF no longer warns "bogus font ascent/descent values (0 / 0)".
This commit will be part of the upcoming MuPDF 1.27.0, so this
commit updates a few pymupdf tests to this new behaviour.
