fix: hide video banner if no videos are available

[omar-sarfraz]

Ticket: ENT-9893

Description: Made some changes to hide videos' banner initially and display it only if videos' section is populated. For the Id's issue, I noticed that we are using hard-coded strings as Ids for Algolia's Index component. I have moved them to a separate file and these Ids are now being used in SearchResults component instead of using a simple Id based on showBetaBadge's boolean condition.

For all changes

• Ensure adequate tests are in place (or reviewed existing tests cover changes)
• Ensure English strings are marked for translation. See documentation for more details.

Only if submitting a visual change

• Ensure to attach screenshots
• Ensure to have UX team confirm screenshots
