Review design of the framework

[VicFalcetta]

As stated by the framework's team, there are some visual aspects that need to be reviewed:

• [x] New 'Required' indicator because the old one was too big
• [x] Our own color identity so it can't conflict or cause problems with dark mode
• [x] Decide if it should stay as a CollectionViewCell or move to a TableViewCell pattern.
• [x] Work on a visual confirmation that the input is ok
• [x] Error message or some feedback when trying to send a form that is not valid

This will be checked and updated as work is done and commented so people can show their opinions and propose changes as needed.

As seen in the image above, shadows were removed due to a bug in code that still needs to be fixing. Also the color scheme was changed, providing both a light and dark mode for the frame work using colors closer to the system. For the "Required" symbol, it was decided to use the SF Symbol asterisk.filled.

This is the new format for the style guide. It has a better explanation of the components and how it will be visually presented.

For the visual confirmation, adding a green checkmark seems a viable option. It is a SF Symbol same as the asterisk for the "Required" designation. When the form is correct this check mark should replace the "Required" symbol.
