Enchant open-with-item action

[1robie]

This pull request introduces a new ClickAction enum to centralize and simplify the handling of click actions, and refactors the logic for loading click actions from configuration files in the InventoryLoader class. The changes improve code maintainability, make action mapping more flexible, and add better error handling and debugging information.

Refactoring and code improvements:

• Added a new ClickAction enum in fr.maxlego08.menu.api.utils to group related Bukkit Action values and provide a convenient method for retrieving associated actions.
• Refactored InventoryLoader to use the new ClickAction enum when parsing click actions from configuration, replacing direct use of Action.valueOf with ClickAction.valueOf(...).asActions(). This allows for more flexible and robust mapping of configuration strings to actions.

Error handling and debugging:

• Enhanced error handling in InventoryLoader by logging a warning message when an invalid click action is encountered in the configuration, including the file path for easier debugging.

Code cleanup:

• Cleaned up imports in InventoryLoader by consolidating multiple import statements into a single wildcard import for utility classes.
• Added the import for the new ClickAction enum in InventoryLoader.…entoryLoader
