Add guidance notification GIF experiment targeting

This is a bespoke advanced targeting config for an experiment. The
experiment struggles to reach the required sample size, so we extended
it relative to a previous iteration by including all locales instead of
just EN. But the necessary strings only landed in 149. And if we
excluded pre-149 versions, we'd be excluding EN users who could see the
message. And we'd be shrinking the audience, counteracting the locale
expansion. So we are including EN users on versions 146 and later PLUS
all locales on versions 149 and later. That means this targeting config
will have no use outside of this experiment, so we can remove it once
the experiment is finished.
