Cleanup image alts

[DeeTheDev]

Fixes #709

This cleans up image alts by:

1. Adding all alt strings in one location - at the top of the 'strings' file
2. Create function that will apply image alt best practices to the localized alt strings - could be helpful in the future if we have to make global alt changes
3. Use function on images
4. Remove redundant alts - mostly in the food images where the image alt name is the same as the product name next to it.
5. All alts are reviewed and mitigated.

In the future, we can use the 'SumaImage' component to render image captions as alts. Rather than creating alt strings in the frontend, we could manually update alts In the admin app.
