The <info>%command.name%</> command pushes translations to the given provider. Only new
translations are pushed, existing ones are not overwritten.

You can overwrite existing translations by using the <comment>--force</> flag:

  <info>php %command.full_name% --force provider</>

You can delete provider translations which are not present locally by using the <comment>--delete-missing</> flag:

  <info>php %command.full_name% --delete-missing provider</>

Full example:

  <info>php %command.full_name% provider --force --delete-missing --domains=messages --domains=validators --locales=en</>

This command pushes all translations associated with the <comment>messages</> and <comment>validators</> domains for the <comment>en</> locale.
Provider translations for the specified domains and locale are deleted if they're not present locally and overwritten if it's the case.
Provider translations for others domains and locales are ignored.
