Integers beyond parsed: info: are always bigint

[buffalojoec]

Description

Since we haven't added any of the JSON-parsed instruction types to the typespec in @solana/rpc-core, any fields that are part of a JSON-parsed transaction instruction default to bigint over number, due to our response processor.

Steps to reproduce

Find a transaction that has a JSON-parsed instruction that uses an integer value that should not be cast to bigint - such as decimals.

You'll see that getTransaction or getBlock will convert this value into a bigint.

Perhaps we just need to fully update the "allowed numeric values" maps to be completely aligned with all jsonParsed types supported by the RPC.

I can't remember, did we do this?
