Might suggest linking here https://deploy-preview-11066--docs-mongodb-internal.netlify.app/reference/operator/aggregation/rankFusion/#selection-pipeline when the docs publish on 6/18

We don't provide explicit links inside of the comment for any of the other stages, so I would prefer we keep that pattern if we can. We link to the stage's documentation in the aggregation builder, so folks can find it there:
Is that link enough? If we feel strongly we can change it.

| \${4:vectorPipeline}: \${7:number} | |
| \${6:searchPipeline}: \${7:number}, | |
| \${8:vectorPipeline}: \${9:number} |
or else, these (search and vector pipeline) will be skipped, right?
