Accessbility issues

[yuzdeng]

For now when you run Siteimprove accessbility checker tool in pagination component there are several issues popup. The main issues are the label missing of page size dropdown and the jumper like the picture show.

The version I test is 3.1.9. The way to fix it is adding the arial-label to the Select and input. Can you add me to your contributor then I can create a pr for these issues? Thanks
