test: test-assert.js fails locally

Version: 10.0.0 (master)
Platform: Windows 7 x64
Subsystem: test. assert

Testing the #18904 locally, I've got this not related error, which I can also reproduce with the last nightly:

assert.js:74
  throw new AssertionError(obj);
  ^

AssertionError [ERR_ASSERTION]: 'The expression evaluated to a falsy value:\r\n\r\n  assert((() => \'string\')()\n      // eslint-disable-next-line\n      ==... strictEqual 'The expression evaluated to a falsy value:\r\n\r\n  assert((() => \'string\')()\r\n      // eslint-disable-next-line\r\n    ...

It seems reasonable: this fragment uses \n on all systems, while this fragment uses \r\n on Windows.

Why does not this test fail on CI?
