fix: update normalize-path to use ECMAScript compliant default import

The `normalize-path` package was previously imported via a namespace import.
However, the ECMAScript specification returns an exotic namespace object from
namespace imports which can never be a function. As a result a namespace import
can not be called. Since the import is directly called it must be imported As
a default import to be ECMAScript compliant. TypeScript by default allows the
non-compliant form even though it can result in runtime errors. The TypeScript
`esModuleInterop` option (recommended by TypeScript) causes TypeScript to error
on non-compliant usage and ensures the correct code is emitted so that the code
can be executed and/or bundled in an ESM environment.
