docs: Clarify that older supervisors use RESIN_ variables

Browse Source 
We add a note on state endpoint docs to use RESIN_ variables. Since users will likely navigate directly to each endpoint, we add the note on the docs for each endpoint, except for endpoints added in >= 7.21.0 (since that version never made it to production).

We also switch some variables that were still referenced as RESIN_ to now use BALENA_.
