Linting for tier badges
As part of the re-do of tier badges, we realized we don't lint the markdown for correctness.
Things like:
- Are the badges in the right order
- Are the asterisks and parentheses correct
Later we can test for minimum of two words in the string, but we don't need to do that now. We have one page that doesn't adhere to this rule: https://docs.gitlab.com/ee/administration/dedicated/ and it's possible we might have more.
