Translate error messages when creating products

[Laurel16]

What? Why?

Closes #9559.

This PR is adding missing translation to for name & price in spree/product in config/locales/{lang}.yml. This fixs the missing error message describe in the issue: https://github.com/openfoodfoundation/openfoodnetwork/issues/9559

What should we test?

Similar to the Steps to Reproduce in the issue: https://github.com/openfoodfoundation/openfoodnetwork/issues/9559

At first I added translation into every config/locales/{lang}.yml but @jibees warned me about this:

Actually, we use Transifex to manage our i18n. Therefore, we only update the en.yml file and then when new keys appears (ie. when PR is merged), instance managers are aware of those key and can translate those new keys inside Transifex. After that, we pull the each file from Transifex.

That's why here, you only need to modify en.yml file ;) Sorry about that! That's maybe not clear enough.

So I just changed en.yml file.

@jibees I prefer to create a new PR, easier than to modify all my yml. I am removing the older one. Tanks 🙂

I'm sorry for the confusion but variant_unit and unit_value are two different things.

* `variant_unit` is something like `weight` or `volume`.

* `unit_value` is a number like `2`.

@mkllnk you are absolutly right, thank you. It is fixed, I hope that help.

Hi @mkllnk, Yes I realise I have added all my files and not just the necessary ones, I am really sorry for the extra work 😔. Thank you 🙏

Hi @Laurel16, Thanks for this pull request! I staged this PR to one of our servers and it seems to work fine. We will only be able to really test the new translations after the translators have edited their translations and those updates have been deployed. We will have to check again in production. For now I think we can safely merge this and move forward. :partying_face: Thanks again!
