[expect-expect] allow additionalTestBlockFunctions to take a regex

[NickBolles]

I would like to do something like this

  "jest/expect-expect": [
    "error",
    {
        assertFunctionNames: ['expect', 'expect*', 'assert*'],
        additionalTestBlockFunctions: ['expect*', 'assert*']
    }
  ]

So that I can modularize assertion functions but still get the expect-expect checking on it. Seems like this would be easy to do by duplicating what assertionFunctionNames is doing

matchesAssertFunctionName

and using it here:
