[FE] Remove Snippets Edit Vue FF
Once ready, we need to remove the Snippets View related FF. This is a big undertaking as we need to convert all existing feature specs that use the page without FF.
What's the difference between this issue and #207239 (closed)? The latter is about enabling the FF by default. This issue is about removing all the flag references in the code base.
~~The reason for the frontend-weight3 is that a lot of RSpec specs will have to be updated (due to template changes between HAML and Vue forms). And all of those changes have to be coordinated with SET.~~ All the heavy lifting ofupdating the RSpecs has been done in !42412 (merged)
