Parsing error on typescript files

[fabio-colella-md]

What version of this package are you using?

• VS Code Standard Extension version: 2.1.0
• "ts-standard": "^11.0.0"
• "typescript": "4.4.4"

What operating system, Node.js, and npm version?

• Mac OS X 12.4
• node v12.22.8
• yarn 1.22.11 (not using npm)

What happened?
Typescript files are not parsed correctly by the extension and I get the following error: Parsing error: Unexpected token :ts-standard.

const thisIsJustATest = (arg: string): boolean => {
  if (arg === "This is a test") {
    return true
  }

  return false
}

export default thisIsJustATest

I have set the extension to "standard.engine": "ts-standard",.

The issue seems to lie in the extension as from command line I cannot see any problem:

$ ./node_modules/.bin/ts-standard --fix src/utils/is-test.ts
✨  Done in 5.40s.

What did you expect to happen?
No error should happen because of typescript syntax.

Are you willing to submit a pull request to fix this bug?
If I understand where the problem lies, I'd be happy to contribute to a fix. I wonder if the setting of the engine is actually being respected, as I've seen similar errors happening with ESLint when not properly configured for supporting typescript.
