- Project listing icons now use the `text-secondary` class
- Group listing icons now use the `text-secondary` class
  - Unnecessary CSS was removed from groups.scss as a result

This updates the groups list UI to match the style of the project list:

- New layout
- Improve loading state when loading group children
- Larger, responsive text
- Icon and text colors changed to secondary
- Smaller button sizes
- Content list description colors were standardized to body text

This is one of many MRs opened in order to improve the overall
internationalisation of the GitLab codebase.

- Update avatar for projects
- Update avatar for frequent items
- Update avatar on "Fork project" page
- Conditionally add rectangular avatar class to autocomplete items

The eslint-plugin-vue upgrade had some breaking changes to
vue/attribute-order which needed to be resolved in order to avoid
disabling the rule entirely
