Disable fail-fast for policy & subscription deployments

[SenthuranSivananthan]

When fail-fast is set to true, GitHub will cancel all in-progress and queued jobs in the matrix if any job in the matrix fails. This property defaults to true.

Reference: https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstrategyfail-fast

In Policy & Subscription deployments, each job is treated independently and we need each to run to completion even if other jobs fail. We are using matrix in these 2 deployments to parallelize tasks.
