Remove snippet visibility link
What does this MR do and why?
The help icon link next to the “Visibility level” label in the snippet form links to https://docs.gitlab.com/user/public_access/ which doesn't explain more than what the form already explains, and that docs page doesn't speak directly to snippets.
This change removes that help link from the snippet form. The code cleanup includes removing the help link component imports, removing the help link property from the component configuration, and removing all the related test code that was checking if the help link worked properly. The form still functions the same way for selecting visibility levels, but users no longer have access to the contextual help documentation.
