Implement ResourceAlreadyExistsException

[DenTray]

Description

What needs to be done?

Create a new exception class ResourceAlreadyExistsException that extends the base Exception class. This class must have a constructor with three parameters:

• entityName (string) — the name of the entity.

• resourceType (of type ResourceTypeEnum) — the type of resource.

• entityNamespace (string|null) — optional, default value is null.

The constructor should automatically set the exception message using the template:
Cannot create {$entity}{$resourceType} cause it already exists. Remove {$entity}{$resourceType} and run command again.
Also, create an enum class ResourceTypeEnum inside the src/Enums directory with the following cases:

• Controller

• Factory

• Model

• NovaResource

• NovaTest

• Resource

• CollectionResource

Ensure proper usage of the enum type for the $resourceType argument in the exception class constructor.
