testcafe compilation failure due to `import type` - requires update to Typescript version 3.8

TLDR:

The version of TS that gets installed with testcafe is version 3.5.3. However, in order to use import Type syntax, which is used by various libraries, such as jest/create-react-app, etc, we need to be on TS version 3.8 at minimum.

When I try to run a TS file with testcafe, the error I get is the following:

All of these *.d.ts use the import Type syntax.
