feat: support .each suite execution by regex

[keroxp]

Support an execution of .each describe/test suite that includes % placeholders. vitest --testNamePattern opts doesn't recognize pattern with% placeholders. So we need to transform the given suite name by replacing % to .+ regexp.

The base branch of this PR is #213.

Fixes #7.

Additionally, Incomplete edge cases still remain. Similar describe/test cases will be matched by the same transformed regular expression. Like:

(1) test.each([...])("my test %s)(() => {})
(2) test.each([...])("my test will be %s")(()=>{})

(2) is also executed by executing (1) and got no result, showing error, because (1) goes to my test .+?.

Ready for review.

LGTM! I love this. Initially I was skeptical of the use of regex, but after seeing the implementation, it should be stable.

@keroxp, @sheremet-va wants to know if we can merge this?

[keroxp]

@ffMathy I'm OK

This introduces a bug. When there are more describes with the same name, you can't run the tests in the last describe.

Example repro:

import { describe, expect, it } from 'vitest'
import { add } from '../src/add'

describe('duplicate describe', () => {
  it('test 1', () => {
    expect(add(1, 1)).toBe(2)
  })
})

describe('duplicate describe', () => {
  it('test 2', () => {
    expect(add(1, 1)).toBe(2)
  })
})

With the above, "test 2" can't be run and will give an error. This worked before.

cc @keroxp. Got an idea for a fix? I tried, but can't understand the code.
