Add aria-label attribute to footnote links

Hmmm I am not sure - is that what a user using a screen reader will want? If they come across a citation, would they want the flow of the text being read to be stopped to read out the reference? Ie, that is what this will do right? Instead of 1 2 3, it will read out the full reference.

Possibly it could be more desirable to read something like "Citation 1", "Citation 2". Whereas reading out the full reference is maybe better left to if the user decides to set specific focus on the anchor link to not interrupt the reading - then it would be aria-described-by right? Although harder to achieve here as there are multiple ways to output the references.

I think first probably need more advice/opinions to help decide way forward here before putting more time into an MR
