Sentry-SDK requirement, unpin minor version

My thinking:

* Avoid Dependabot spam for harmless version bumps. (sentry-SDK
  has the most upgrades by an order of magnitude)

* In princple, there should be no breakage, b/c they do semver and
  "minor version when you add functionality in a backward compatible manner"

* This is dev tooling; it shouldn’t be a source of friction.

* As it stands: I'm not thoroughly reviewing these anyway (b/c of the spammyness)

The alternative would have been to "just freeze" it; if we ever run into
problems because of the unpinning I certainly will.
