fix(connector-besu): set contract bytecode field's max length to 49154

[petermetz]

Prior to this commit the Besu connector's API validated requests when deploying solidity
contracts via their bytecode such that the length of the bytecode parameter
cannot be longer than 24576 characters, but instead it should have an upper limit of
49154 characters because each byte is represented as two characters in hex.

See https://ethereum.stackexchange.com/a/47556 regarding the maximum length of the bytecode.
2 + (24576 * 2) = 49154 meaning that hex stores each byte in 2 characters and that
there is a 0x prefix (2 characters) which does not count towards the EVM 24576 bytecode limit."

Fixes #3636
