Amend content in Visas cannot be sponsored dropdown

Feedback from GiT is that we shouldn’t link to the ‘Apply for your visa’ GiT page from the ‘Visas cannot be sponsored’ dropdown on Find courses pages.

This is because the ‘Apply for your visa’ page is about courses that offer visa sponsorship. The content on this page is not applicable to courses that do not offer visa sponsorship.

While we’re at it, I would also like to make a couple of minor changes to the ‘Student visas can be sponsored’ and ‘Skilled worker visas can be sponsored’ dropdowns.

Changes proposed in this pull request

• Update link text from as an international student" to a non-UK citizen
• Alter conditional logic to remove content if visa_type is student_visa and if sponsorship_availability is available
