- [x] I have read the contribution docs, and understand what's expected of me.

### Link to the page on docs.getdbt.com requiring updates

I reviewed this [PR](https://github.com/dbt-labs/docs.getdbt.com/pull/9177) on 14 May and noticed some content was repeated so reusable snippet should be created to tackle this

### What part(s) of the page would you like to see updated?

website/docs/docs/build/latest-metrics-spec.md

website/docs/docs/build/metricflow-commands.md

website/docs/docs/build/validation.md
