feat: add anilist metadata provider

Description: Added AniList Metadata Provider. The AniList provider allows us to fetch detailed metadata for manga series directly from AniList's database.

Key Features Introduced:

Smart Title Matching: Implemented advanced logic for title matching that accounts for variations in punctuation, capitalization, and spacing, ensuring high accuracy in metadata retrieval.
Year and Title-Based Filtering: The provider includes functionality to filter series based on their release year and title, enhancing the precision of metadata matches.

Note on Testing:

As I'm currently expanding my knowledge of Spring and its testing frameworks, this submission does not include unit tests for the new provider. I've conducted thorough manual testing with my library, ensuring the provider's functionality meets our application's standards and performs as expected across various scenarios. I plan to delve deeper into Spring's testing capabilities to add comprehensive tests in the near future.

Important Configuration Note:

For the AniList Metadata Provider to function optimally, series within the library must be organized in a specific manner. The root folder name plays a critical role in this process, as it should be named appropriately to include the series title and publication year (Has to be the original year it was released). This naming convention ensures precise extraction and matching of metadata. For example:

├── Berserk (2003)
│   ├── Berserk v01 (2003) (Digital) (danke-Empire).cbz
│   └── Berserk v02 (2004) (Digital) (danke-Empire).cbz
├── Bleach (2004)
│   └── Bleach v01 (2004) (Digital) (AnHeroGold-Empire).cbz
...

Proper naming facilitates accurate title and year extraction, crucial for the metadata provider to perform as intended.

P.S I don't use kotlin much so if there is a better way to do things do let me know!
