Features relating to the sizing API (Upsun):

• Support "resources" in the environment:sync (sync) command.
• Add --resources-init option to five more commands:
  • backup:restore
  • environment:activate
  • environment:branch (branch)
  • environment:merge (merge)
  • environment:synchronize (sync)
• At "default" and "minimum" as keywords for the resources:set command (use
  the newly exposed defaults in the API).

Other changes:

• Make push --activate ensure an environment is active, even when no changes
  were pushed.
• Fix "Failed to extract zip" on Windows (by updating credential helpers).
• Print PHP built-in warnings by default (without needing -v).

• Bump giggsey/libphonenumber-for-php from 8.13.29 to 8.13.30.
• Skip rerunning SSH cert check when SSHing from the CLI.
• Highlight green regions in the project:create (create) command.
• Support IPV6 ip address validation (#1405) (thanks @hanoii).
• Set SSH log level to DEBUG3 when the CLI is in debug mode.
• Fix metrics for multi-instance grid hosting.
• Use the new backups API for restoring.
