feat(forge): scripts should output formatted json to broadcast/

[OliverNChalk]

Component

Forge

Describe the feature you would like

It would make sense if forge script produced json files that are formatted in-line with how out/**/*.json is formatted. Currently, the written json is compact & single-line.

Current broadcast/:

{"transactions":[{"hash":"0x81ca81143efbd8e0300a14558ba3d3bf7c449ca40714bde1398f35bda863894c","type":"CALL","tx":{"type":"0x02","from":"0x70997970c51812dc3a010c7d01b50e0d17dc79c8","to":"0xa0ee7a142d267c1f36714e4a8f75612f20a79720","gas":"0x6aa4","value":"0xde0b6b3a7640000","data":"0x","nonce":"0x0","accessList":[]}}],"receipts":[{"transactionHash":"0x81ca81143efbd8e0300a14558ba3d3bf7c449ca40714bde1398f35bda863894c","transactionIndex":"0x0","blockHash":"0x831d6dfc4f6464bf18f81fa82580400f3d2f77ab1f51f138874d43e6e6d78487","blockNumber":"0x1","from":"0x70997970c51812dc3a010c7d01b50e0d17dc79c8","to":"0xa0ee7a142d267c1f36714e4a8f75612f20a79720","cumulativeGasUsed":"0x5208","gasUsed":"0x5208","contractAddress":null,"logs":[],"status":"0x1","logsBloom":"0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000","effectiveGasPrice":"0xe6fa7a58"}],"libraries":[],"pending":[],"path":"broadcast/fund_owner.sol/31337/run-latest.json","returns":{},"timestamp":1656959845}
