Updated lang path getting mechanism

[m0stwan1ed]

Defining of localization folder has been updated: Laravel 9 has new lang folder path: '/lang', this causes an exception: 'resources/lang doesn't exists!' during the files creation.

In Laravel 5.0 (also available in newer version) App::langPath() method has been added, which helps to get lang folder absolute path, so there is no need to manually build path to lang folder anymore

Thank you @m0stwan1ed for you contribution. I was reading through pending PR and I included an option to specify the language directory. Apart from that, do you consider this PR needed?

@rmariuzzo i think #170 can be extended to use langPath() as a fallback

This way, it does two things:

1. Support subsequent updates to this directory out of the box without needing the config file updated.

2. Allows users specify their own directory in case they don’t want to use the native lang folder that ships with Laravel.

@wilpat also there's another request that does that too: #166

I'm willing to combine both effort when possible.
