Display tier to users
## Problem
Feature access in GitLab.com is dependent on both subscription tier and version. In current state, it can be difficult for a logged-in user to know what their current tier/version is, as this is not easily displayed they have access to. Our docs list which tier+version is needed to have access to particular features, but there's no way for a user to make use of this info unless they are also an admin.
* Tier = Premium, Ultimate, Free, Dedicated
* Version = 15.4.0, 15.3.4, etc.
## Proposal: Tier
_**Version display has spun out into a separate issue: https://gitlab.com/gitlab-org/gitlab/-/issues/428062**_
**Summary:** Add a tier badge next to the Project/Group name on the project and group overview pages as well as on the group/project list pages (same as was done for Free tier in https://gitlab.com/gitlab-org/gitlab/-/issues/345514+)
1. For MVC iteration, we can add the badge without a hover-over CTA
2. Design specs can be found [here](https://www.figma.com/file/zZu5MU8507k6iMbMRO0SRk/Display-tier-badge-at-Group-and-project-level?node-id=3%3A3840)

1. Add tier to navigation bar next to Project as a badge (see example [here](https://gitlab.com/gitlab-org/gitlab/-/issues/410170#note_1388988088 "Pricing tier is not obvious from a project/group")). This would be the most easily visible location, but may not align with navigation plans or could be cluttered/distracting. - _feedback from Nav team was that this is NOT a preferred option._
2. Add tier to a Project's home page - perhaps at the top section, even below `Project ID`.
1. {width="841" height="250"}
3. Add to help page with version info - _This would require adding project-level awareness to this page, which is not currently available and would add significant complexity._

## Proposal: Version
:white_check_mark: Version details have been added to the `Help` page (https://gitlab.com/help/) \> `Help`, accessible to all logged-in users.
