feat: allow extension in mutator import

[henkerik]

Status

Description

Fix #1232 . Orval doesn't support ES modules yet. When adding "type": "module" to the package.json file (and setting TS moduleResolution to node16 or nodenext), the imports should contain an extension. So:

import ... from './some-mutator'

should become:

import .. from './some-mutator.js'
