Update sway book and developer quickstart with new command set

We have a [section](https://fuellabs.github.io/sway/master/book/forc/plugins/forc_client/index.html#signing-transactions-using-forc-wallet-cli) in the sway book under `forc-client` explaining how to use it with `forc-wallet` (since usage of `forc-client` generally means usage of `forc-wallet`).

We also have a [developer quickstart](https://fuellabs.github.io/fuel-docs/master/developer-quickstart.html) that might need a little bit of love after the changed set of commands gets released. Since they are in different repos it might be possible to miss them but we should probably update them as soon as we release this new set of commands in the next release of `forc-wallet`

Open the forc-client section on signing transactions and the developer quickstart linked in the issue. Compare their forc-wallet command examples with the new command set once it is released. Done means both pages consistently document the released commands.
