Port spinach tests to rspec feature specs

Logic is the same, just now ported, while this feature was being
improved anyway in this branch.

Resolves #20961

features/project/badges/build.feature

-Feature: Project Badges Build
-  Background:
-    Given I sign in as a user
-    And I own a project
-    And project has CI enabled
-    And project has a recent build
-
-  Scenario: I want to see a badge for successfully built project
-    Given recent build is successful
-    When I display builds badge for a master branch
-    Then I should see a build success badge
-
-  Scenario: I want to see a badge for project with failed builds
-    Given recent build failed
-    When I display builds badge for a master branch
-    Then I should see a build failed badge
-
-  Scenario: I want to see a badge for project with running builds
-    Given recent build is successful
-    And project has another build that is running
-    When I display builds badge for a master branch
-    Then I should see a build running badge
-
-  Scenario: I want to see a fresh badge on each request
-    Given recent build is successful
-    When I display builds badge for a master branch
-    Then I should see a badge that has not been cached
