[BUU] Improve Product Search Keywords

[filipefurtad0]

What we should change and why (this is tech debt)

We have a test for this feature in which we assert only if the data is saved on the respective fields. We should improve it by testing the search feature on the products page, making sure it finds products according to the added search keywords.

Relevant spec: https://github.com/openfoodfoundation/openfoodnetwork/blob/78a1726bdc3bf61194a9e68c112865da2df3c5b6/spec/system/admin/products_spec.rb#L494
