IDEA: Add push_options parameter

[chicco785]

push_options are not set as environmental variables, due to that, they cannot be passed to the shell script

Maybe, the feature https://github.com/creyD/prettier_action/issues/80 is a work-around for that. Having proper git pushes is a hard task - and maybe, another action should be used (and this action can focus on nice running of prettier)

@koppor in dev I think this is now tackled :)
