testing: fix reference to B.N in docstring

Currently, a documentation reference to a struct member (such as [B.N])
does not result in it being rendered as a link, and thus the square
brackets remain in the rendered documentation which is mildly confusing.

The issue can be seen at
https://pkg.go.dev/testing@master#hdr-b_N_style_benchmarks

Remove the square brackets to fix.
