Paul Gottschling e8b7d3527a Catch misuses of the Var component (#51081) ...

Closes #29905

Add a Vale style rule to catch docs pages in which there is a single
instance of a Var. This ensures that Vars reuse information as intended.

Also fix single-instance Vars that violate the rule. For the most part,
this means either:

- Instructing the user to assign the Var, meaning that there are no
  easy-to-miss Vars hiding in a configuration snippet
- Removing unnecessary Vars, e.g., if an example command is meant to
  illustrate a possibility and is not mean to be copied and pasted
- Fixing mistakes in Var usage, e.g., a Proxy Service address variable
  that has two possible names, `teleport.example.com` and
  `example.teleport.sh`.
