Disallow asynchronous import statements

[matthewbastien]

Description

Asynchronous import() statements can appear anywhere in a file and make it difficult to see at a glance what dependencies that file has. For example:

const test = await import("./some/file");

Add an ESLint rule that disallows this style of import.

Tasks

• Required tests have been written
• Documentation has been updated
• Added an entry to CHANGELOG.md if applicable
