0.38.1

Fixes

• build: include sentry-actix optionally when release-health is enabled (#806) by @lcian
  • sentry-actix is now being included as a dependency only when explicitly added, either as a direct dependency or through the actix feature flag of the sentry crate.
  • Due to a mistake in the Cargo.toml, it was previously being included as a dependency by default when using just the sentry crate with default features.
