Remove jest vue3 check quarantine jobs from backport MR pipelines

Problem

The jest vue3 check quarantine and jest-with-fixtures check quarantine jobs are unnecessary to run in backport MRs and cause an inflated runtime.

These two jobs together cause a total of ~17 minutes for backport MR pipelines. Removing these from Tier 1 and Tier 3 pipelines would save us ~16% in runtime / operational costs (approximately 14 hours of compute time weekly)

This change will not sacrifice quality.

Proposal

Remove jest vue3 check quarantine jobs from backport MR pipelines, while preserving quality.
