Refactor ParticleConfig with Jackson, add ParticleData models, and update dependencies

Replaced JSON-Simple with Jackson for particle configuration parsing. Introduced `ParticleData` and `ParticleInfo` models for structured data. Updated `ParticleConfig` structure for clarity and modularity. Added Jackson and Lombok dependencies in `build.gradle.kts`.

+/**
+ * Represents the configuration data for a particle effect, including its name, type, display properties,
+ * animations, and permissions. This class is primarily used for managing particle data in the context
+ * of custom particle effects and animations.
+ * <p>
+ * Fields:
+ * - particleName: The unique name of the particle effect, used internally.
+ * - displayName: The name displayed to the user.
+ * - particleType: The type of the particle effect, which corresponds to an {@link APartType}.
+ * - lore: Additional descriptive text associated with the particle effect.
+ * - displayItem: An item representation for display purposes in order to visually represent the effect.
+ * - permission: The permission string required for accessing the particle effect.
+ * - packagePermission: A specific permission string linked to a grouped set of effects.
+ * - frameDelay: The delay between animation frames, in milliseconds.
+ * - repeat: The number of times the particle animation should repeat.
+ * - repeatDelay: The delay between repeat executions, in milliseconds.
+ * - randomOffset: A random position offset applied to the particle effect for variances.
+ * - stationary: Determines if the particle effect remains static or follows movement.
+ * - frames: A map defining animation frames for the particle effect. The key is an identifier, and the
+ *   value is a list of {@link ParticleInfo} objects representing the frame's particle configuration.
+ * <p>
+ * Methods:
+ * - getAPartType(): Converts the particleType string field into an equivalent {@link APartType} enum value.
+ *   This allows for accessing predefined properties of the particle type.
