ci: skip the suite for Docs markdown too

Docs/API_CACHE.md and Docs/StoreKit.md are prose with no runtime surface, same
as the root docs.

Both patterns stay single-star, so they match those two levels and nothing
deeper. Hutch/API_REFERENCE.md still runs the suite: a .md living inside the
source tree is close enough to code to be worth the five minutes.
