can we add an overview of metaMap usage to the official docs?

When reviewing and discussing Nextflow programming techniques with others, I often find myself landing on the topic of the "metaMap" and why its so useful for Nextflow programming.

However after reviewing the official docs pages here https://www.nextflow.io/docs/latest/script.html I realized that it does not seem to be covered. Which leads me down a rabbit-hole of "where did I originally learn about the metaMap?" and "where are the docs that I can easily share about this?".

It seems like there are some docs here;

• https://training.nextflow.io/advanced/metadata/#first-pass

and a section about it here;

• https://nf-co.re/docs/contributing/modules#what-is-the-meta-map

I feel that this is such an important concept, it should be 'graduated' to the official docs page (https://www.nextflow.io/docs/latest/) for easier discovery and sharing.

The meta map is just a map, which the script page talks about. But it is a common pattern. We are working to consolidate our various docs resources and add more target content for things like this. Stay tuned
