Excessive information about repository types

[exalate-issue-sync]

h3. As a user

I want to think in terms of repositories and not have to care about the type of repository or where it is stored
So that the menu’s and navigation is easier and focused on actions without exposing too much of Infrahub’s internals

h3. Description

Currently, the sidebar menu has options for both Repository and Read-Only repository. This part could instead be done with a Generic so that we only have one repository item.

h3. Acceptance Criteria

When a user visits the menu of Infrahub. Then only one repository option is present, options are instead presented when creating a repository.
