getsentry/sentry-java 8.46.0 on GitHub

Collections returned by scope (e.g. getBreadcrumbs, getTags, getAttachments) are shared state and should not be mutated. (#5541)
- Previously, when going through CombinedScopeView, we were returning a copy where mutations didn't show up in the underlying scopes.
- This has now changed in order to reduce SDK overhead.
Date objects returned by SDK data model getters are shared state and should not be mutated. (#5603)
- Previously, these getters returned defensive copies for some date fields.
- This has now changed in order to reduce SDK overhead.
