Switch to native date picker

[juliusknorr]

Summary

Move to native datetime picker component as the old one has quite some issues especially with accessibility.

Shortcuts are now adapted to match the implementation of the reminders feature in files/talk.

Super nice! Only some small changes:

• Use radio buttons for the icon (in files reminders the reminder can't be changed once set, so radio buttons could not be used, but it makes sense here)
• Add a short indication of the date for the "This weekend" and "Next week" items. Eg. "This weekend - Sat, Aug 26, 8:00 AM"

Use radio buttons for the icon (in files reminders the reminder can't be changed once set, so radio buttons could not be used, but it makes sense here)

I'm not sure about that. The radio button only be selected as long as the day hasn't changed or the end of the day hasn't been reached. I feel without a radio button it is more logical as a single time action to set the date accordingly.

Add a short indication of the date for the "This weekend" and "Next week" items. Eg. "This weekend - Sat, Aug 26, 8:00 AM"

I like the idea, unfortunately there seems to be no way to properly localize the short form in terms that the order might be different (in Germany it would be 26. Aug for example) If accepting that we always have the same order no matter of which locale to use, then we could do that, otherwise I'd rather leave it out.

Looks good. Just one minor suggestion.
