nitrokey-3-firmware: opcard.use_se050_backend not working with NK3 mini

The NK3-Mini is not working with the se050 backend.

I updated the nk3-mini: ./nitropy-v0.4.46-x64-linux-binary nk3 update --version v1.6.0-test.20231218

> gpg --card-status

gpg can find the device as smartcard.

Then I changed the backend to use se050: ./nitropy-v0.4.46-x64-linux-binary nk3 set-config opcard.use_se050_backend true

Now, if I run card-status gpg freezes without any output.

I have to unplug the nk3 to run nitropy again (seem it hung).

Using Debian stable I run the following gpg-version:

gpg --version gpg (GnuPG) 2.2.40 libgcrypt 1.10.1
