Add prettier plugin support for Gherkin

[jjorgenson-aya]

🤔 What's the problem you're trying to solve?

To help enforce style standards, prettier is often used for files like TypeScript, PHP, etc. Having (official) support for Gherkin would be beneficial for git hooks.

✨ What's your proposed solution?

Add plugin for Prettier that formats Gherkin.

⛏ Have you considered any alternatives or workarounds?

Current formatters seem to only be supported through VSCode or Monaco.
This prettier plugin seems limited in options if you want slightly different configurations.

📚 Any additional context?

Does an implementation of a Prettier plugin for Gherkin already exist, such as the one found at https://github.com/mapado/prettier-plugin-gherkin?

Some of these plugins are very subjective. Each to their own - and each language will likely "bleed over" some of their thoughts to their language equivalent feature files.

I would encourage you to use whichever one/s make most sense to you, there are a few out there as linked.
