Update trial and opensource pipeline_triggers plan limits to 25k

What does this MR do and why?

As seen in #350577 (closed), the limits for pipeline_triggers are not consistent across all plans for GitLab.com. This is because either new plans were introduced or the limits were not migrated when the plan names were updated. This MR adds a migration to update the non-paid plans (opensource and trials) to 25k.

We confirmed in #350577 (comment 1791881087) that customers under the relevant plans are all well under 25k. We also have a confirmation to proceed with this change here.

Partially resolves #350577 (closed).
