When creating a new repository with multiple versions (e.g., el8 and el9), there's a display inconsistency between the two systems:

Content Sources frontent side:

• Versions are displayed with a comma: el8, el9

• This is the correct and desired format

Image Builder frontend side :{}

• Versions are displayed without a comma: el8el9

This is incorrect and hard to read

expected:

we should ad comma between version
