Setting git remote preferences fails (no such config variable)

Bug Report

Summary and Bug Description

Executing axii config --global git_remote_preferences.git.h2t.iar.kit.edu ssh from https://git.h2t.iar.kit.edu/sw/armarx/meta/axii/-/blob/main/docs/advanced_users/README.md#git-remote-preferences yields to the following error of not being able to set the config variable git.h2t.iar.kit.edu, which is a part of the variable name that has actually been requested to be set.

Current Behavior

axii config --global git_remote_preferences.git.h2t.iar.kit.edu ssh yields

No such config variable 'git.h2t.iar.kit.edu'.

You can set it as follows:

    axii config --global git.h2t.iar.kit.edu "<new_value>"

Expected Behavior

Output should (as previously) be

Set 'git_remote_preferences.git.h2t.iar.kit.edu' to ssh.
``


## Steps to Reproduce

Update axii to the latest stable version and execute ``axii config --global git_remote_preferences.git.h2t.iar.kit.edu ssh
