Fix bugs discoverd by e2e tests

Tip

This PR implements simple PRC version control. Basically it introduces a new rpcVersion field responsible for RPC version. It affects the MarshalJSON method. The only exception is BlockHeader, because if we implement this method for this structure, all structures BlockWith* containing BlockHeader will use this method and we will see only BlockHeader. In these cases we simply make the L2Gas field nil if necessary. In addition, in #2401 the rpcVersion field is used in some calculations in the fee estimation.

Below are the key changes grouped by theme:

Removal of L2 Gas Fields:

• Removed L2Gas field from the DataAvailability struct in core/transaction.go.
• Removed L2Gas field handling in adaptExecutionResources functions in adapters/core2p2p/receipt.go and adapters/p2p2core/receipt.go. [1] [2]

RPC Method Versioning:

• Added versioning constants V0_7 and V0_8 in rpc/handlers.go.
• Introduced version-specific RPC methods in rpc/block.go and rpc/handlers.go, such as BlockWithTxHashesV0_7, BlockWithTxsV0_7, and BlockWithReceiptsV0_7. [1] [2] [3]

Fee Estimation Adjustments:

• Removed FeeEstimateV0_7 struct and integrated versioning into the FeeEstimate struct in rpc/estimate_fee.go. [1] [2]
• Updated the EstimateFeeV0_7 and EstimateMessageFeeV0_7 methods to use the new versioning approach. [1] [2]

Test Updates:

• Modified tests in rpc/block_test.go and rpc/estimate_fee_pkg_test.go to accommodate the changes in fee estimation and RPC method versioning. [1] [2] [3]
