Session verification fixes and bump SDK to v0.0.1-october23 (#1954)

* Fixes vector-im/element-x-ios/issues/1868 Incorrect `is_verified` flag after successfully running verification flow
- the inner user_identity isn't automatically updated when the flow finishes, needs to be fetched again from encryption
- also replaces `UserIdentity.is_verified` with `Device.is_cross_signed_by_owner`
- depends on matrix-org/matrix-rust-sdk/pull/2775
