[oak] Fix boolean parse for CLI

[yzang2019]

Describe your changes and provide context

Problem:
In x/dex/client/cli/tx/tx_register_contract.go, arguments [need hook] and [need order matching], only check against the string true. For example, if a user capitalizes the word, the flag is going to be set as false. Use strconv.ParseBool

Testing performed to validate your change

Tested manually with cli after building sei chain
