Request for Feature Enhancement: Support for Multiple JSON Keys in Mihdan Index

Dear Mihdan Plugin Development Team,

I hope this message finds you well.

I am currently using your plugin, Mihdan Index Now, for managing the Google Indexing API on my WordPress site. The plugin has been incredibly useful, and I appreciate all the work you have put into it. However, I have a specific requirement that I believe could greatly benefit many users, including myself.

Feature Request: Would it be possible to add support for multiple JSON keys within the Mihdan Index Now plugin for the Google Indexing API? This enhancement would help in better managing API quotas and provide a more robust solution for users who need to work with multiple keys.

Current Use Case:

• We are experiencing quota limitations with a single JSON key.
• The ability to rotate or switch between multiple JSON keys would help us manage these quotas more effectively.
• A user-friendly interface to add, remove, and manage multiple keys would be greatly beneficial.
