Keybase upgrade to 6.0.2 using installed yum repository fails

I am running Fedora 35 with keybase installed. But I started having failures on keybase upgrade, because GPG signature is incorrect.

```
$ LC_ALL=C.UTF-8 sudo dnf upgrade keybase
keybase 49 kB/s | 3.3 kB 00:00
Dependencies resolved.

It seems it were signed by different key than repository expects.

Start by reproducing the failure with `dnf upgrade keybase` on Fedora 35 and inspect the configured repository key URL. Compare the RPM signature key ID with the imported `code_signing_key.asc`; done means the 6.0.2 package verifies successfully through the installed repository without disabling GPG checks.
