Add "View details" to toast shown after "Enable in project/group"

On the toast created in ee/app/assets/javascripts/ai/catalog/pages/ai_catalog_agents_show.vue, we want the message, "Agent enabled in %{name}." to link the project name to the agent link for that project/group, e.g. /groups/gitlab-duo/-/automate/agents/276/

We also want this behavior for flows.

We can ignore /ee/app/assets/javascripts/ai/catalog/pages/ai_catalog_agents.vue (and ai_catalog_flows.vue), as we will remove the code to show a toast there.
