Wrong tooltip value/formattedValue shown if category scale contains labels that convert to numbers within 0..labels.length

### Expected behavior

In the tooltip for values with a category scale the formattedValue is showing a completely wrong value if the category scale contains labels that convert to numbers within 0..labels.length.
E.g. if there are 5 labels and one of them is "1" for items having that value "1" a wrong tooltip value is returned.

### Current behavior

Currently the nth label is shown for a value of "n" and not the label "n".

### Reproducible sample

https://github.com/chartjs/Chart.js/pull/12106

### Optional extra steps/info to reproduce

I think this is due to scale.category.js _getLabelForValue ignoring the type.
