ci: remove superseded ensure actions pin job DK-5938

[raffis]

This is an automated PR

Current situation

So far we validated our action pipelines in order to ensure all actions have been pinned to a digest.
However github has introduced a new feature which is a simple org wide setting which renders this job not needed anymore.

Proposal

Remove job.

Summary by cubic

Removes the redundant SHA-pinning validation job from the pull request workflow for DK-5938. GitHub’s organization-wide setting now enforces pinned actions, so CI no longer runs this duplicate check.

^{Written for commit e8e1eb6. Summary will update on new commits.}
