refactor: ♻️ 4.1 support (#508)

* Remove type hint for for...in variable

* Remove another typed for...in variable

* Fix production_no_workshop.tres format

* Fix production_workshop.tres format

* Use custom function instead of type_string

* keep type in `load_mods()`

* refactor: ♻️ `fix_method_super()` use `erase` `insert` instead of `sub`

_ModLoaderModHookPreProcessor.fix_method_super() erased everything after the function body, leaving only the first function in a script.

* refactor: ♻️ remove inline type in for

* style: 🔥 remove white space

* refactor: ♻️ engine version check

* fix: ✏️ fix typo

* refactor: ♻️ engine_version as int

* refactor: ♻️ use version hex and link to PR

* fix: 🐛 fixed type

* refactor: ♻️ use RegEx.sub() and add back text

* Update addons/mod_loader/internal/mod_hook_preprocessor.gd

* Update addons/mod_loader/internal/mod_hook_preprocessor.gd
