Subject: [PATCH] fix: correct SHA256 typo, update machine images, scope build
 workflows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix CIRCLE_SHA2256 typo (extra '2') in build-linux-amd64 Build step;
  same class of bug fixed in #120/#121 but this instance was missed
- Upgrade ubuntu-2004:202201-02 → ubuntu-2204:current for both Linux
  machine executor jobs (amd64 and arm64)
- Add branch/tag filters to build_linux, build_windows, build_macos
  workflows so they only run on master or v* tags instead of every branch
