Draft PR here: #5526

Here's what the table looks like currently:

dbt Core version	Manifest version
v1.7	v11
v1.6	v10
v1.5	v9

Here's what it will look like after adding one new row:

dbt Core version	Manifest version
v1.8	v12
v1.7	v11
v1.6	v10
v1.5	v9

Do we also want to add a new column to indicate which manifest schema version is associated with dbt Cloud KoLV (Keep on Latest Version)?

dbt Core version	dbt Cloud KoLV	Manifest version
v1.8	✅	v12
v1.7		v11
v1.6		v10
v1.5		v9

@dbeatty10 i love the table idea! i'm going to loop in the docs leads here (@matthewshaver and @nghi-ly). if I'm understanding this correctly, i wonder if it's easier to just have a sentence in there somewhere so it's clear that kolv = latest manifest version. that way we don't have to maintain the column for every new version?

'e.g. if you select 'Keep on latest version,' you'll always use the newest dbt Core version and its corresponding manifest schema. for example, if the latest dbt Core version is v1.8 with a manifest schema of v12, then 'Keep on latest version' will use manifest schema v12.'
