borgmatic 1.9.2

• #441: Apply the "umask" option to all relevant actions, not just some of them.
• #722: Remove the restriction that the "extract" and "mount" actions must match a single
  repository. Now they work more like other actions, where each repository is applied in turn.
• #932: Fix the missing build backend setting in pyproject.toml to allow Fedora builds.
• #934: Update the logic that probes for the borgmatic streaming database dump, bootstrap
  metadata, and check state directories to support more platforms and use cases. See the
  documentation for more information:

• #934: Add the "RuntimeDirectory" and "StateDirectory" options to the sample systemd service
  file to support the new runtime and state directory logic.
• #939: Fix borgmatic ignoring the "BORG_RELOCATED_REPO_ACCESS_IS_OK" and
  "BORG_UNKNOWN_UNENCRYPTED_REPO_ACCESS_IS_OK" environment variables.
• Add a Pushover monitoring hook. See the documentation for more information:
