Shopify redesing and update

We need to improve some things in our Shopify store:

- Improve SEO
- Upgrade shopify to newest version
- Change the small logo displayed on tabs (we have it already but it needs to be inserted)
- Redesign the checkout page and experience
- Change product page to have variants visible in buttons and not in a displayed menu to know beforehand if it is available
- Have all the available colors visible below the product in the sections where all the products are displayed
- Filters improvement in all the sections
- Change email address of order confirmation and check functionality of emails and customer experience after they buy.
