chore: crates metadata and documentation

[ematipico]

Summary

This PR updates various crates inside the repository to contain the correct metadata and files in order to have a starting point for those crates to be published to crates.io.

With this PR, I published the following crates:

• rome_json_parser
• rome_json_formatter
• rome_js_parser
• rome_js_formatter

Unfortunately, I haven't found a decent automated workflow to publish the crates yet. My initial idea was to use cargo-workspaces, which is like a lerna for rust projects.

I am not sure this would work correctly though, because this tool uses tags to "understand" which crates to publish.

Test Plan

Current CI should pass

Changelog

• The PR requires a changelog line

Documentation

• The PR requires documentation
• I will create a new PR to update the documentation
