UX Issue: inform to the user that all the accounts created using metamask can be recovered using nemonic

### Describe the bug

Account created using metamask are linked to the nemonic and can be recovered using account creation feature if needed. Account creation in metamask is deterministic and each time user will get exactly the same accounts created.

If the user is re-installing metamask and use nemonic to recover their account they will see only the first account in the wallet. Some users use the import account option to recover other account they created previously. This is related to issue: https://github.com/MetaMask/metamask-extension/issues/12525

Thus we need to communicate this more clearly to the user that account creation will create the same set of account always.

Start by reviewing the account creation and recovery flows described in this issue, then read the related issue #12525 and the linked design document. Done means the UX clearly explains that MetaMask account creation is deterministic and tells users how to recover additional accounts after restoring a mnemonic.
