access(contract) and access(account) documentation

[jacob-tucker]

Current Behavior

Right now access(contract) and access(account) indicate that the scope is only in the current contract or current account, respectively.

This is not true. If you declare access(contract) or access(account) in an interface in one contract, and implement that interface in another contract, you can access the var/function in both contracts.

Expected Behavior

Improve the docs to better indicate the actual scope.
