Add Git Repository form shows empty permission content and non-working help link until a git url is entered

Description of problem:
The "Add Git Repository" has a "Show configuration options" expandable section that shows the required permissions for a webhook setup, and provides a link to "read more about setting up webhook".

But the permission section shows nothing when open this second expandable section, and the link doesn't do anything until the user enters a "supported" GitHub, GitLab or BitBucket URL.

Version-Release number of selected component (if applicable):
4.11-4.13

How reproducible:
Always

Steps to Reproduce:

1. Install Pipelines operator
2. Navigate to the Developer perspective > Pipelines
3. Press "Create" and select "Repository"
4. Click on "Show configuration options"
5. Click on "See Git permissions"
6. Click on "Read more about setting up webhook"

Actual results:

1. The Git permission section shows no git permissions.
2. The Read more link doesn't open any new page.

Expected results:

1. The Git permission section should show some info or must not be disabled.
2. The Read more link should open a page or must not be displayed as well.

Additional info:

1. None
