chore: Reduce MMI trigger machine size

[Gudahtt]

Description

The check-mmi-trigger job was using a medium machine, but the work performed during this job is trivial and doesn't require a medium machine. It has been reduced to small.

Related issues

No related issue, just a minor CircleCI credit usage reduction.

Manual testing steps

See that the trigger MMI job still passes.
