v31 folds in the remainder of the review patch (hooray!) and makes a
change to the 401 handling. If the server doesn't tell the client why
a token request failed, but we see that we got a 401 Unauthorized, the
error message now suggests that the oauth_client_secret setting is
unacceptable.

(If anyone out there happens to be testing this against real-world
implementations, I would love to get your feedback on this failure
mode. I can no longer get Entra ID to require a client secret during a
device flow, the way I used to be able to with Azure AD.)

I've also made the default device prompt translatable.
