feature: send force parameter to deployment api

[vitormorales]

Summary

• Forward the --force flag value to the formspree API call, so the API is aware when a forced deployment is requested.
• This is needed updating HMAC secret using the CLI.
  If a key already exists and the user wants to update it, should use this flag.
• Default is false

Please provide more descriptive PR comment.

Also this isn't accurate anymore:

  yargs.option('force', {
    alias: 'f',
    describe: 'Skip verifying that secrets reference environment variables',
    type: 'boolean',
    default: false
  });

Sorry for that. Updated the description either in code and PR. I checked and we still skip any invalidKey when --force is used.
