Merge branch 'missing-raw-snippet-access-spec' into 'master'

Add missing security specs for raw snippet access

## What does this MR do?
It extends the project snippets access security specs to cover raw snippet paths as well.

When I was researching snippets for !7256, I noticed that specs existed for the HTML show view of project snippets but not the raw view. Seeing as this is a spec that is checking for access regressions on places where sensitive information might be kept, I thought it would be a good idea to cover the raw snippets access too.

To balance out the karma of adding in extra tests I also changed the tests to all use an `empty_project` spec.

## Are there points in the code the reviewer needs to double check?

With the aim of making the specs easier to read, I restructured some of them to use context blocks for each type of snippet.

I've used the same access rights defined for the show snippet paths for the raw snippet access. 

## Why was this MR needed?

To catch security regressions on raw snippet access for projects.

## Screenshots (if relevant)
