* PHP unit tests were failing due to a change in the Github actions environment.
* E2E tests were failing because of that issue (they rely on port 8084 which is used in ubuntu 20 environment) and because of an issue with @woocommerce/e2e-environment
* update min version in docs and tests
* update woocommerce-admin.php
* update docker versions
* one more 5.3
* Docker image: back to min versions
* fix main file's min PHP to 7.0, same as Woo Core and readme.txt
