Make QuickLink Resource Installation Optional

[daniil-nedostup]

Is your feature request related to a problem? Please describe.
Currently, Quick Link resources are automatically created for every Git Server defined in the values.yaml. This behavior can cause deployment failures if the Custom Resource Definition (CRD) for Quick Links is not available in the cluster. In such cases, users might prefer not to create Quick Link resources for some or all Git Servers.

Describe the solution you'd like
Introduce a configurable option in the values.yaml file that allows users to control whether Quick Link resources are created for each Git Server.

Describe alternatives you've considered
Users could fork the chart and modify it to avoid creating Quick Link resources, but this adds maintenance overhead.

Additional context
This feature would enhance the flexibility of the Helm chart, especially in environments where some CRDs may be unavailable or unnecessary.
