Fix pagination accessibility issue

What is the context of this PR?

ONSDESYS-472

As per the ticket:

• Removed "Go to" from "aria-label" attributes.

• When "aria-current" is set to true a default "aria-label" will only have the text set in position variable which is "Page " ~ currentPageIndex ~ " of " ~ totalPages(Eg When aria-current is over the 3rd page, voice over only reads Page 3 of 4 instead of previous Current Page(Page 3 of 4))

• The ticket also mentions about adding "aria-hidden" to svg icons. We have this already so we don't need to make any changes to it

Also user who raised this issue used total validator to check the issue. As total validator works with a paid tier. I've used wave to test the page.

It looks like we do have some svgs in the icon macro that return an svg that doesn't have aria-hidden and doesn't have aria-labeledby so you might need to take a look into this. One example is the "crest" svg.

I have aria-hidden=true for all the icons which doesn't have aria labelled by. Let me if that's okay
