Merge #1732: chore(core)!: rename SyncResult to SyncResponse

3b03c7b chore(core)!: rename `FullScanResult` to `FullScanResponse` (Leonardo Lima)
1411cb8 chore(core)!: rename `SyncResult` to `SyncResponse` (Leonardo Lima)

Pull request description:

  fixes #1647

  <!-- You can erase any parts of this template not applicable to your Pull Request. -->

  ### Description

  As mentioned in #1647 issue, the usage of `Result` in Rust is conventionally meant to be an enum type with error variant, and it's appropriate here.

  It should be `SyncResponse` instead, as it's the most appropriate alongside the other types `SyncRequest` and `SyncProgress` already being used.

  <!-- Describe the purpose of this PR, what's being adding and/or fixed -->

  ### Notes to the reviewers

  <!-- In this section you can include notes directed to the reviewers, like explaining why some parts
  of the PR were done in a specific way -->

  ### Changelog notice

  <!-- Notice the release manager should include in the release tag message changelog -->
  <!-- See https://keepachangelog.com/en/1.0.0/ for examples -->

  - Change `bdk_core::spk_client`'s `SyncResult` to `SyncResponse`.
