### Please describe the problem.
git-annex-remote-googledrive uses SETCREDS and GETCREDS to let git-annex handle the credentials. According to the [documentation](https://git-annex.branchable.com/design/external_special_remote_protocol/) it should be stored inside the git-annex branch when using hyprid or pubkey encryption. However, this does not happen. Even setting embedcreds to yes does not change anything.

### What steps will reproduce the problem?
    git annex initremote testremote type=external externaltype=googledrive prefix=test keyid=<key> encryption=pubkey
or

    git annex initremote testremote type=external externaltype=googledrive embedcreds=yes prefix=test keyid=<key> encryption=pubkey

I can see that gpg is called after SETCREDS and I would have expected there to be an additional config "credentials":

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
Of course ;) In fact. I've actually never used embedcreds. I just had an [issue](https://github.com/Lykos153/git-annex-remote-googledrive/issues/48) raised about it on github.
