Fix blockhash retrieval error by upgrading @solana/web3.js to ^1.98.0

[iamramtin]

Problem:

When using older versions of @solana/web3.js (such as 1.33.0), the following error occurs:

"failed to get recent blockhash: Method not found at Connection.getRecentBlockhash"

This error is caused by the removal of the getRecentBlockhash method in Solana RPC, which older versions of @solana/web3.js attempt to call.

Solution:

Upgrade @solana/web3.js to version ^1.98.0, which resolves the error by using the updated getLatestBlockhash method in the Solana RPC.

Steps to Reproduce:

1. Use an older version of @solana/web3.js (e.g., 1.33.0).
2. Attempt to send a transaction using sendAndConfirmTransaction.
3. Receive the error: failed to get recent blockhash: Method not found.
