							Add -f shorthand flag for prune --force  
						
						 
						
						... 
						
						
						
						The docker builder prune command has a shorthand `-f` flag for `--force`:
    docker builder prune --help
    Usage:	docker builder prune
    Remove build cache
    Options:
      -a, --all                  Remove all unused build cache, not just dangling ones
          --filter filter        Provide filter values (e.g. 'until=24h')
      -f, --force                Do not prompt for confirmation
          --keep-storage bytes   Amount of disk space to keep for cache
Given that `buildx` can be used as a drop-in replacement for the native build
commands, it should match the UI, and also have a shorthand flag.
This patch also updates the flag's description to be in line with the docker commandline
With this patch applied;
    buildx prune --help
    Remove build cache
    Usage:
      buildx prune [flags]
    Flags:
      -a, --all                  Remove all unused images, not just dangling ones
          --filter filter        Provide filter values (e.g. 'until=24h')
      -f, --force                Do not prompt for confirmation
      -h, --help                 help for prune
          --keep-storage bytes   Amount of disk space to keep for cache
          --verbose              Provide a more verbose output
    Global Flags:
          --builder string   Override the configured builder instance

						When following this pattern:
  buildx build --arg FOO
Where we want to pull `FOO` from env, currently we always set `FOO`
regardless if the `FOO` env var is even set.
This change makes it so that `FOO` would only be set if it has been set
in the env (even if it is set to empty).
