Add version consistency check

[PrincessStevenson (PrincessStevenson)]

What

This PR adds a standalone Version Consistency Check workflow to the repository.

It runs Skyscanner/version-consistency-check@v1 as a separate check in GitHub so version mismatches show up clearly on the PR.

The check is configured to fail when inconsistencies are found.

Why

This introduces language version mismatch checks in the repository.

It is part of the strategic action for INL-3290 / INC-4850 and is outlined in COMET-2757.

The check looks for mismatched build and runtime language versions across repository configuration, workflow setup, and Dockerfiles where supported.

actions/checkout@v6 is inconsistent with the rest of the repo (other workflows use actions/checkout@v4), and may not be a valid major tag for the checkout action in this repository’s dependency policy. Suggest switching this to actions/checkout@v4 for consistency (or pin to whatever version is used elsewhere).

Suggested change

	- uses: actions/checkout@v6
	- uses: actions/checkout@v4

[Copilot]

runs-on: ubuntu-latest-small is not a standard GitHub-hosted runner label (the repo’s other workflows use ubuntu-latest). If this repository/org doesn’t provide a runner with that label, this workflow will never start. Recommend using ubuntu-latest (or an existing, documented self-hosted runner label used in this repo).

Suggested change

	runs-on: ubuntu-latest-small
	runs-on: ubuntu-latest

Closing this rollout PR because we should not use the internal version-consistency-check action in public repos.
