Please correct SOFT value for Thin Italic instance

[thlinard]

The Thin Italic fvar instance has <coord axis="SOFT" value="100.0"/> while all other instances, Italic or Regular, have <coord axis="SOFT" value="0.0"/>

Per fonttools/fontbakery#3213, the default opsz value should not be made elidable.

Indeed! There were inconsistencies at the time.

But the "9 pt SuperSoft Thin Italic" instance should be "9 pt Thin Italic", like the Regular instance "9 pt" (this is because the Thin Italic fvar instance has <coord axis="SOFT" value="100.0"/> while all other instances, Italic or Regular, have <coord axis="SOFT" value="0.0"/>).
