Subject: [PATCH] test(screen): adjust screen state per stylua #31441

Before:
screen:expect({        | screen:expect({
  grid = [[            |   grid = [[
    {10:>!}a        |  |     line ^1                   |
    {7:  }b        |   |     {1:~                        }|*4
    {10:>>}c        |  |   ]], messages={ {
    {7:  }^         |  |     content = { { "\ntest\n[O]k: ", 6, 11 } },
    {1:~          }|*9 |     kind = "confirm"
               |       |   } }
  ]]                   | })
})

After:
screen:expect([[         | screen:expect({
  {10:>!}a            |  |   grid = [[
  {7:  }b            |   |     line ^1                   |
  {10:>>}c            |  |     {1:~                        }|*4
  {7:  }^             |  |   ]],
  {1:~              }|*9 |   messages = { {
                 |       |     content = { { "\ntest\n[O]k: ", 6, 11 } },
]])                      |     kind = "confirm"
                         |   } },
                         | })
