docs(specs): add realtime_sendRawTransaction method for MegaETH (#1122)

Add the missing realtime_sendRawTransaction endpoint which submits a
transaction and returns the receipt in a single call, timing out after
10 seconds. Added as a manual exception (x-bot-ignore) since the
Daikon workflow skips non-eth_ prefixed custom methods.
