A missing `prettier` formatter is silently ignored

[sschuberth]

Describe the bug

Generated files under "requests" have tabs instead of spaces although prettier is configured otherwise.

To Reproduce

I have a .prettierrc with

{
    "useTabs": false
}

and run openapi-rq -i http://localhost:8080/swagger-ui/api.json -o src/api --format prettier.

The generated *.ts files have tabs instead of spaces.

OpenAPI spec file

n/a

Expected behavior

Spaces instead of tabs should be used according to the prettier configuration.
