BoAT User Guide-BoAT IoT Framework SDK Compilation-Better translation and correct number of wallets

[mia-BoAT-Mariner]

Describe the bug
Note：Since the PlatON, PlatONE, FISCOBCOS and Venachain blockchain wallet codes reuse the Ethereum wallet code in large numbers, it is necessary to enable Ethereum for any one of these three to be enabled.
注：由于PlatON，PlatONE，FISCO BCOS和Venachain四个区块链钱包代码大量复用以太坊的钱包代码，所以这三个任意一个使能时，都需要把以太坊使能。

Better translation reference as below:

Note: Since the four blockchain wallet codes including PlatON, PlatONE, FISCO BCOS and Venachain all largely reuse the wallet code of Ethereum, Ethereum needs to be enabled when any of these four are enabled.
