Axelar bridge docs use js, pythons, and Foundry increasing skill set and tools needed.

ethers js library can be use to both encode and send transactions eliminating need for python and Foundry/cast

encoding

        // Define the data type and value
        const types = ['string'];
        const values = ['hello, world!'];

        // ABI encode the data
        const abiEncoded = ethers.utils.defaultAbiCoder.encode(types, values);

        // Compute the Keccak-256 hash of the ABI encoded data
        const keccakHash = ethers.utils.keccak256(abiEncoded);

This was partially addressed in #88, where Python code was replaced with JS using the ethers.js library.
