Vue-jest: V4.0.0-beta.1: ts-jest warnings for non-Typescript code

[syropian]

vue-jest: V4.0.0-beta.1

I am not using Typescript anywhere in my app. If I dont have typescript as a dev dependency my tests fail with this error:

Unable to load the module "typescript". Using "ts-jest" requires this package to be installed. To fix it:
        ↳ install "typescript": `npm i -D typescript` (or `yarn add --dev typescript`)

If I install typescript as a dev dependency, all my tests pass, but all my tests that test regular .js files (not .vue files) give this warning:

ts-jest[versions] (WARN) Version 24.0.0 of jest installed has not been tested with ts-jest. If you're experiencing issues, consider using a supported version (>=22.0.0 <24.0.0). Please do not report issues in ts-jest if you are using unsupported versions.

Jest config:

"jest": {
  "moduleFileExtensions": [
    "js",
    "json",
    "vue"
  ],
  "setupFiles": [
    "<rootDir>/resources/assets/js/__tests__/utils/mockument"
  ],
  "testPathIgnorePatterns": [
    "<rootDir>/resources/assets/js/__tests__/utils/"
  ],
  "transform": {
    "^.+\\.js$": "babel-jest",
    "^.+\\.vue$": "vue-jest"
  },
  "moduleNameMapper": {
    "^@/(.*)$": "<rootDir>/resources/assets/js/$1"
  }
}

I am running 5.0.0-alpha.4 and seeing this same issue (I'm on Vue 3). Could this be a regression?
