Convert issue list checkboxes to native (#23596)

Use native instead of fomantic checkboxes in issue list. Benefits
include no more JS pop-in on load and perfect a11y.

Before, with JS pop-in:

After, Firefox on macOS:

After, Chrome on macOS:

I opted to not do styling yet but I see that the inconsistency between
browsers may already be reason enough on doing it. I think if we style
them, there should be one global style, including markdown ones which
currently have custom styling.
