fixup: make binary cache nuclear option more general

[cole-h]

Recently, we added a binary-cache-detsys-v1.sqlite file, and these instructions would not remove that.

Motivation

Context

Summary by CodeRabbit

• Documentation
  • Clarified the cache cleanup command in the narinfo-cache-negative-ttl setting notes.
  • Updated the example to remove all matching binary cache SQLite files, not just a narrower versioned subset.

Poem

🐇 I hopped through the docs with a twitchy nose,
A wider glob for the cleanup shows.
One tiny tweak in the cache-file light,
Keeps the stale bits out of sight.
Hoppy tidy, neat and sweet!
