auto.config.ts breaks when tsconfig.json "module" is "es2015"

**Describe the bug**

It seems that _auto.config.ts_ as described in the docs doesn't when user's project specifies `"module": "es2015"` (not `"commonjs"`) in its _tsconfig.json_.

This is a problem upstream in _@endemolshinegroup/cosmiconfig-typescript-loader_, but I wanted to leave this issue here for other people encountering the error.

**To Reproduce**

A fast way:

1. Copy auto.config.ts to your nearest project with auto.
2. Change your tsconfig.json module setting to one preserving ES6 imports (e.g. `"es2015"`)

A way I'm 100% sure will crash as expected:

1. Clone https://github.com/system-ui/theme-ui
2. Checkout `3a92b715cb83481004dd91b8fe19d5147711411a`
3. Run `yarn auto shipit`

**Expected behavior**

Config copied from the docs works.

**Screenshots**

```
⇝ yarn auto shipit
yarn run v1.22.5
$ /home/hasparus/workspace/theme-ui/node_modules/.bin/auto shipit
TypeScriptCompileError: Failed to compile TypeScript: Unexpected token 'export'
at Function.TypeScriptCompileError.fromError (/home/hasparus/workspace/theme-ui/node_modules/@endemolshinegroup/cosmiconfig-typescript-loader/src/Errors/TypeScriptCompileError.ts:20:12)
```

**Environment information:**

I don't expect it to be relevant but info crashes too.
Should `info` command crash when the config is broken?

Start by reproducing the failure with auto.config.ts, a tsconfig.json using module "es2015", and the documented yarn auto shipit or yarn auto info commands. Read the configuration-loading path and the reported @endemolshinegroup/cosmiconfig-typescript-loader entry points; done means establishing whether this repository can handle the configuration or must update the upstream dependency, with the command succeeding.
