feat: Find lang() strings and update localization keys

@kenjis see pls fork https://github.com/neznaika0/codeigniter...age-finder

* The command lang :find searches for translation (lines lang('File.key')) files in the default APPPATH folder and ignoring APPPATH . Language/ path.
* The command is able to recognize nested keys normally (File.form.placeholder.text). After the update, the developer only needs to add the necessary translation, and not search through the entire lang() code
* Bad lines are skipped.
* Added some tests. After checking, the created files are cleared. I need a response for a reliable PR.

Known issues:

! Each update overwrites comments in the language file

! php-cs-fixer may not work for appstarter project (if require-dev disabled)
! I would like to add translations where they possibly should be, for example, Config/Validation

! It would be nice to add hints (boolean) if the translation contains variables. For example, File.form.placeholder.text {vars} will indicate the presence of some dependencies in the phrase

1. Update all in APPPATH and default locale:

Code:

$ php spark lang:find

2. Find and update translations in a specific folder (+ subfolders) and select a new locale:

Code:

$ php spark lang:find --dir Controllers/Translation --locale ru

3. Find translations and show table with new translations:

Code:

$ php spark lang:find --dir Controllers/Translation --show-new 
$ php spark lang:find --dir Controllers/Translation --show-new --locale ru

4. Detailed output. Can be added to other options:

Code:

$ php spark lang:find --verbose --dir Controllers/Translation --show-new
$ php spark lang:find --verbose --locale ru

Code:

aleksandr@aleksandr-debian:~/www/ci-demo$ php spark lang:find --dir Controllers/Translation --verbose --show-new
