Update "Call to Action" to "Call to action"

In general, the pattern UI, inserter, and block editor uses sentence case, not titlecase, for all UI. Should we update the pattern category to match? See also "Post format", "My patterns", etc.

Thanks for reporting @jasmussen - It makes sense.

I can see this is coming from core, specifically here. I'll open a trac issue and create a PR for it later today.

Thanks so much. I don't think it's super urgent, but good to track!
