Implement getTransactionByBlockNumberAndIndex Handler with tests

[AryanGodara]

Resolves #68 Some of the fields are still missing; and I'm going through both the starknet and Eth APIs to see what those corresponding fields are.

{
    "name": "starknet_getBlockWithTxs",

@ermvrs, I need your help with this The resulting block may be pending and I can't figure out a way to check this in the response.

By comparing the openAPI specs of the two possible responses (given below); I wrote the following code, as these fields are present only in pending blocks (according to the openAPI doc here)

  // Check if the block is pending by looking for pending-specific properties
  const isPendingBlock = (block: any): boolean => {
    // Check for required pending block properties
    return 'parent_hash' in block && 'timestamp' in block && 'sequencer_address' in block &&
          'l1_gas_price' in block && 'starknet_version' in block;
  };

  if (isPendingBlock(response.result)) {
    // If it's a pending block, return an error response
    return {
      code: 7979,
      message: 'Starknet RPC error',
      data: 'The block is still pending. Pending blocks cannot be processed.',
    }
  }

And here are the specs for the Block Responses:

"PENDING_BLOCK_WITH_TXS": {
    "title": "Pending block with transactions",
    "description": "The dynamic block being constructed by the sequencer. Note that this object will be deprecated upon decentralization.",
    "allOf": [
        {
            "title": "Block body with transactions",
            "$ref": "#/components/schemas/BLOCK_BODY_WITH_TXS"
        },
        {
            "title": "Pending block header",
            "$ref": "#/components/schemas/PENDING_BLOCK_HEADER"
        }
    ],
    "additionalProperties": false
},

"BLOCK_WITH_TXS": {
    "title": "Block with transactions",
    "description": "The block object",
    "allOf": [
        {
            "title": "block with txs",
            "type": "object",
            "properties": {
                "status": {
                    "title": "Status",
                    "$ref": "#/components/schemas/BLOCK_STATUS"
                }
            },
            "required": [
                "status"
            ]
        },
        {
            "title": "Block header",
            "$ref": "#/components/schemas/BLOCK_HEADER"
        },
        {
            "title": "Block body with transactions",
            "$ref": "#/components/schemas/BLOCK_BODY_WITH_TXS"
        }
    ]
},

It was a suggestion to change a var to const. I pushed new changes, but the CI isn't running after the new commit
