[SM Cloud Licensing Trials] Add/Update min version for SM cloud licensing trial workflows

Problem

In [SM Cloud Licensing Trials] Iteration 1.1: Impl... (&16046 - closed), the creation flow of the SM Ultimate on Cloud Licensing trial record was implemented. [SM Cloud Licensing Trials] Iteration 1.2: Upda... (&16047) plans to utilize it to allow provisioning/deprovisioning, activation, and usage of this trial type.

When addressing the GitLab side, a conversation about supported versions was raised. It was concluded to require a min version for the SM Ultimate on Cloud Licensing trials. The version still needs to be determined while working on the project.

Proposal

• The trial email confirmation email needs to be updated to mention the required GitLab minimum version for using the SM Ultimate on Cloud Licensing trials
• The same minimum version should also be set in the instance activation workflow to restrict trial activations to it
• The error message without cloud compatible subscription in CloudActivations::ActivateService should also be updated depending on the GitLab version:
  • For GitLab versions < minimum version, send without cloud compatible subscription
  • For GitLab versions >= minimum version, send a new error message such as without cloud compatible source or without cloud compatible subscription or trial
  • The SubscriptionActivationErrors Vue component in the GitLab frontend will need to be updated to handle and translate this new error message (ex: see SUBSCRIPTION_NOT_FOUND_ERROR_TITLE and SUBSCRIPTION_NOT_FOUND_ERROR_MESSAGE). We should check with UX and Product regarding the error message verbiage.

Possible proposal:

Title:

Your subscription or trial cannot be located

Error message (we may need the link to the landing page where a user can start a new SM cloud licensing trial. If not available yet- consider splitting off the error messaging updates into a new issue)

You may have entered an expired or ineligible activation code. To request a new activation code, %{purchaseSubscriptionLinkStart}purchase a new subscription%{purchaseSubscriptionLinkEnd}, {startTrialLinkStart}start a new trial%{startTrialLinkEnd}, or %{supportLinkStart}contact GitLab Support%{supportLinkEnd} for further assistance.

Result

Require and communicate a GitLab min version to the customers via the trial confirmation email and activation workflow (as an error).
