Generate a JSON or YAML file with all pinned essential tool and dependency versions (for docs)

[mitchmindtree]

This could be used to output a markdown table of all binaries exposed from the flake.nix. E.g.

Tool	Version	Description
essential-builder	0.5.0	The essential block builder implementation.
essential-node	0.5.0	The essential node binary.
essential-rest-client	0.5.0	A CLI http client for interacting with a node and/or builder.
pint	0.5.0	The CLI for the pint programming language.

Also could be used to generate a markdown of all essential-repo dependency versions.

crate	version
essential-types	0.8.0
essential-hash	0.5.0
etc	etc

To-Do

• [ ] Create a nix/bash script that, given a list of package names and versions, produces the tables in JSON or YAML.
• [ ] Use the generated file to derive markdown tables for docs (in getting started guide and README and all places that mention versions).
