[Tutorial] subkey inspect Alice returns nothing

[fleupold]

#1795 renamed the subkey restore subcommand to subkey inspect. However, the command subkey inspect Alice from the substrate tutorial is no longer returning any output.

This makes it hard to recover the seed for the pre-funded account. Would it be possible to update the tutorial with a working command?

To temporarily workaround, the seed happens to be 0x416c696365202020202020202020202020202020202020202020202020202020

The functionality of converting "Alice" into a 256bit hex was lost in the latest update, but I updated the tutorial to use the latest commands and made a note that "0x416c696365202020202020202020202020202020202020202020202020202020" is simply "Alice" in hex

Step 2: Add Alice to your network

Alice is a hard-coded account in your blockchain's genesis block configuration. To make your life easier, this account is automatically pre-funded with currency and made a "super user" to your blockchain upgrade system. To access the "Alice" account, you must use her unique seed, which happens to be a 256 bit hex encoding of the string "Alice":

0x416c696365202020202020202020202020202020202020202020202020202020

Optionally, you can see the details generated by this seed by opening a new terminal, and using the installed substrate/subkey package:

subkey inspect 0x416c696365202020202020202020202020202020202020202020202020202020

This is now further updated to support the latest crypto in Substrate and the Substrate UI.

Alice's URI is now: //Alice using sr25519, and can be directly put into the seed for the substrate UI

./target/release/subkey inspect //Alice works great for me
