Use unique glm_content for updated trial CTAs
requested to merge gitlab-org/gitlab#350378-use-unique-glm_content-for-updated-trial-ctas into master
Sets a unique glm_content
value for the updated “Get Free Trial” CTAs.
All other trial-related CTAs continue to use their same glm_content
values.
I also found one other place where we could replace a hard-coded SaaS trial entrypoint URL with the new saas_trial_entrypoint_url
helper.
