[New Feature] Optional CLI Argument for ProveTxHash

[koloz193]

Motivation

In the current system we use the L2 rpc to grab the commitBatch transaction hash and the proveBatch tx hash. There are some scenarios where the L1 will get this proveBatches transaction before it is reflected in the RPC response. We want to add an optional cli argument for the proveTxHash that will supersede what's returned in that call.

Acceptance Criteria

• Add new proveTxHash cli argument
• Update function to use the proveTxHash when supplied, properly handling when both are empty
