Upload should only show repositories you are authorized to upload to

When a user has the nx-component-upload privilege, the Upload tab will show them all of the repositories — even ones that they aren't authorized to upload to. This can be especially confusing and detrimental to the user experience when there are a large number of repositories.

Attempting to upload to these repositories will return an error, however, they should not be an option in the first place.

Expected**

The Upload tab should only show repositories that a user is authorized to upload to.
