format: treat noinspection as comment directive

Used by some versions of GoLand and friends,
https://www.jetbrains.com/help/go/disabling-and-enabling-inspections.html

New versions use `//goland:noinspection` instead/additionally, but it
doesn't hurt much to support the older (and still the only documented)
one.
