feat(*): adding themePicker to Samples

[ChronosSF]

• Updates astro-components to 1.1.0 for theme picker
• Adds theme picker to all non-theming samples

@DiLazarova , one thing that I think we didn't test properly is that if the the "open sample" button is to the right, then the theme picker looks a bit weird between two buttons of different roundness and size:

Maybe we need to style the dropdown to better match the other controls on the bottom.

Please, also check how the samples behave in dark mode, I think we have to modify some styles so they look better in dark mode.

Should look like this in dark mode

This is also relevant for Avatar component.

Double check for React

All the components should be in dark mode

The descriptive text should be gray 200

There are some dark gray background around all the samples.
