API for Getting Supported Tokens Info on the Faucet

[AtelyPham]

Description

Currently, the cryptocurrency faucet does not have an API to retrieve information on supported tokens. This feature is necessary for developers who are building on top of the faucet and need to programmatically get the list of supported tokens.

Proposed Solution

Add a new API to the Faucet Backend repo to get supported tokens info. Ideally, the endpoint will return a list of supported tokens with their corresponding information such as token name, symbol, address, and supported typed chain ID.

Acceptance Criteria

• A new endpoint is added to the Faucet Backend repo that returns supported tokens info.
• The response should include the token name, symbol, address, and supported typed chain ID.
• Documentation for the new endpoint should be added to the API documentation.
