Move 'Explore Snippets' Spinach feature to Rspec

## What does this MR do?
It moves the `features/snippets/discover.feature` Spinach test to a Rspec feature.

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

As part of deprecating the Spinach test suite.

Move 'Search Snippets' Spinach feature to Rspec

## What does this MR do?
Moves the Spinach feature `features/snippet_search.feature` to an RSpec feature `spec/features/snippets/search_snippets_spec.rb`.

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

The search results page URL was being visited directly in the original Spinach test, using an encoded search query and specific parameters to trigger the snippet searches. I have changed the RSpect feature to fill in the search box on the snippets dashboard page to retrieve results to cover the missing test coverage on the search box and to avoid the feature test from relying on the implementation details of the search URL structure.

## Why was this MR needed?

As part of deprecating the Spinach test suite.

Prior, an administrator viewing a project's Labels page would see _all_
labels from every project they had access to, rather than only the
labels of that specific project (if any).

This was not an information disclosure, as admins have access to
everything, but it was a performance issue.

When unauthorized the border on the counter in issue boards didn't span the whole way around
