Inline snapshot escapes character ($) even though it's not necessary

[jonasb]

Describe the bug

If a string in the inline snapshot includes the character $ it's escaped with a backslash in the output (\$) even though it's not needed. This causes eslint to complain.

Reproduction

https://stackblitz.com/edit/vitejs-vite-gswmr2?file=src/test.test.ts

import { test, expect } from 'vitest';

test('hello', () => {
  // when run, this string will be added to the inline snapshot: '"string with \$ character"'
  expect('string with $ character').toMatchInlineSnapshot();
});
