Add missing front matter for keywords and description

[bravo-kernel]

Currently, the website pages/markdown files are missing front matter variables description and keywords which will be used as html meta tags.

Both variables should be added so the markdown looks similar to:

---
id: quick-start
title: Quick Start
sidebar_label: Quick Start
description: Some appropriate page-specific description
keywords:
  - Pester
  - Powershell
  - etc.
  - etc.
---

Do you know if keywords will help DocSearch? Because they're not used by search engines anymore AFAIK, so if not we could ignore that.

Description meta-tags are created using the first lines of content (no headings) when not specified explicitly. In many cases those are fine. Should we focus on adding a quick 1-2 line intro per file when missing maybe? Thoughts?

Ah, I needed to figure out what I intended here but I remember again:

• only relates to (all) static .mdx files in folder repo/docs
• your suggestion for description sounds great: "first lines unless that doesn't work". E.g. for the Unit Testing within Modules example above I think we would need to make something up like Detailed instructions on the two Pester methods available to perform unit tests and mocks within Powershell Modules.
• IMO nobody really knows if keywords are not used for SEO anymore but why take the risk plus we might exclude ourselves from other tools that use keywords if we choose do not add them

Hope this clarifies things 💃

Of course not needed for the auto-generated files in repo/docs/commands. I see I already auto-generate those fields.

@fflaten can this one be closed now? The canonical did its job as well btw, good job!

Yes, but it doesn't look like the descriptions have been indexed yet on Google.

Great, I will close. As far as Google is concerned, I am getting used to wait for weeks 🤦‍♀️
