Make Enter submit the form on both products and orders admin

[luisramos0]

What? Why?

Closes #4437

It feels like too much copy paste for such a simple feature. I left the first commit so reviewers can see the alternative directive approach. The alternative approach was not working for the orders page, so I decided to go with ng-keypress.

On the orders page we only add the behavior to free text fields.

What should we test?

Products search /admin/products - type something on quick search and press enter, see the results being updated.
Orders search /admin/orders - type something on any of the text fields (Invoice number, email, first name and last name) and press enter, see results being updated

Release notes

Changelog Category: Added
Pressing enter will submit the search form on admin orders and products.

Good enough IMO 👍

I think I prefer the option in the first commit. It's a lot more DRY, no?

[luisramos0]

yes, agree but i couldnt make it work for orders page. Do you want to have a look? Could be a very simple thing.

I'm of the opinion that better done than nothing, at least here. Then, we can spend some time improving it but knowing this is already done.

so @Matt-Yorkley, which way do you want to go?

Hi @luisramos0 ,

Thank you for your notes on the issue and in this PR.

I verified that the PR makes hitting enter work, as an alternative to manually pressing the Filter Results button on:

• Products page
  -- Quick search field
• Orders Page
  -- Fields Invoice number, Email, First name begins with, Last name begins with

Good to go,
Thank you!
