Add which EE version is included in the Free trial

Description

https://about.gitlab.com/free-trial/ mentions EE everywhere, but it's not clear which version of EE customers will be able to try.

Proposal

• Indicate which EE version is included in the free trial
• add a link to the features page

@amara what do you think? Now that we will drive much more people on this page through the new menu, it's a good opportunity to add more info on this page.

Somehow a duplicate of https://gitlab.com/gitlab-com/www-gitlab-com/issues/1232. Closing.
