[BUG] Date buttons don't have 'button' role #387
Description
Describe the bug
The date buttons have their role set to gricell instead of button, which confuses some accessibility software, for example Dragon Naturally Speaking
Steps to reproduce
Visit https://vanilla-calendar.pro/
Start Dragon Naturally Speaking
Use the "Show Links" voice command
The calendar buttons are not highlighted by Dragon Naturally Speaking
Expected behavior
The calendar buttons should be enumerated by Dragon Naturally Speaking
Additional context
This can probably be solved by wrapping the buttons in a span with role=gridcell and display: contents, and removing role=gricell from the buttons.
