[Feature] Automatically transform special characters in test name to avoid file overwrite in results folder (e.g. video recording)

[xsjcTony]

Consider the following test

test.describe('this is a test suite', () => {
  // these are all `**-a-b-**` ❌
  test('a > b', async () => { expect(1).toBe(1); });
  test('a = b', async () => { expect(1).toBe(1); });
  test('a < b', async () => { expect(1).toBe(1); });
  test('a + b', async () => { expect(1).toBe(1); });
  test('a # b', async () => { expect(1).toBe(1); });

  // this will result in `**-a---b-**` ✅
  test('a - b', async () => { expect(1).toBe(1); });

  // this will result in `**-a-test-b-**` ✅
  test('a test b', async () => { expect(1).toBe(1); });
)}

For the first 5 tests, the video recorded for earlier ones will be overwritten by the latest one, since the folder name all resolves to **-a-b-** that those special characters got ignored. I don't think it's developer's responsibility to make test name fs.safe, since it makes sense to use special characters like > or < to replace greater than or smaller than, etc.

Unfortunately fixing this will break existing users.

:( Fine, it makes sense. But I think it could be better if this could be mentioned explicitly in the doc so others won't fall into the trap
