refactor: Alias the alai function (#1209)

The `alai` function works using the Lambda context object to parse the
invoked function name. As an acronym for AWS Lambda Account ID it is not
particularly memorable or descriptive. This PR aliases the function as
`getAccountIDFromContext` to make it a little more understandable.

Tests pass.
