[Tree] Incorrect use of aria-checked in Tree Multi Select variants #2599
Description
Provide a general summary of the issue here
In Multi select (https://storybook.sanomalearning.design/?path=/story/navigation-tree--multi-select) and Multi select with Badges (https://storybook.sanomalearning.design/?path=/story/navigation-tree--multi-select-with-badges) variants the built in accessibility checker shows problems with wrongly used aria attributes, namely "aria-checked"; The problem here is, that according to documentation, "aria-checked" is not mentioned as to be used with role="row" (https://w3c.github.io/aria/#aria-checked);
🧑💻 We could use tree-item, then aria-checked possible, or remove aria-checked and add aria-multiselectable to the role=treegrid element, and use aria-selected for both single and multi select
Another thing is, that in input type="checbox" there is "aria-checked" present, when it is not needed for it, as "input" has built in semantics and doesn't require ARIA (https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Reference/Attributes/aria-checked)
🧑💻 Make sure to also check the indeterminate state after the fix has been done
