[Feature]: Set locale when pulling products, categories and cart from the API

[rafalcymerys]

How the project can be improved?

Spree's endpoints support ?locale parameter, which can affect the language of returned entities.
We should include it in our requests, based on the language selected on the frontend.

What are the acceptance criteria?

• When fetching product list, products are returned with names in user's language
• When fetching product details, product name and description is returned in user's language
• When fetching categories, their names are in user's language
• When fetching cart, product names are in user's language
• When fetching orders, product names are in user's languages
