Group billing page should contain options to buy now and start a trial
Currently, if you view a free group billing page it only gives you the option to start a trial, there is no option to buy now.
We should display two options on this page:
"View paid products & upgrade" > This should link to the plans page within the customer's app so the user is able to view/select the plan that is best for them. https://customers.gitlab.com/plans
"Start a trial" > This link should match the existing trial links on the page. https://customers.gitlab.com/trials/new?gl_com=true
We should also only have one CTA for starting a trial.
We should remove the large group avatar image from the page.
Known issues/long term plans
A longer-term discussion is to decide if we want to continue to have separate billing pages between the user settings and group settings as it creates a host of issues and if we do want separate pages, what should that experience be. Existing known issues in the current setup include, if a user starts a user or group trial the other billing page still views them as free. When upgrading it also doesn't remember the source (group settings or user settings) in the customer app so the customer will have to self select if the upgrade is for a user or group during the checkout process. To start we will fix the existing page so users can upgrade and start a trial, we will need to address the points above when deciding the ideal future state of this page.
