Rename DaService method extract_relevant_txs to extract_relevant_blobs

[dubbelosix]

Description

• Renaming the following functions
• extract_relevant_txs to extract_relevant_blobs
• extract_relevant_txs_with_proof to extract_relevant_blobs_with_proof

The reason for this rename is to make a clearer distinction in the naming so that developers know this refers to DA blob transactions and not the rollup transactions
