I don't think this is the correct language.. something more like "customize the names of the dbt-generated meta fields in your snapshot tables"

small sugg that's not a blocker: maybe have the header outside the versionblock and tell users on 1.8 and lower that this feature is only avail in 1.9 and higher or versionless so they know?

++ we need to do this for all new features!

In [Versionless](/docs/dbt-versions/upgrade-dbt-version-in-cloud#versionless), you can now customize the names of the meta columns created by dbt in the [snapshot table](/docs/build/snapshots#snapshot-meta-fields) using the `snapshot_meta_column_names` configuration.

Let's add an example

Note, if you rename snapshot columns without updating the existing table, it will cause an error. It's recommended to use this feature for new snapshots or update your existing tables before committing a column name change.
This feature will also be available in the upcoming 1.9 release of dbt Core.
