Add robots option to frontmatter and edit the markdown of the "category" guides

[ppcano]

• Add robots metatag to frontmatter
• Allow editing the content of the categories. The API section supports this option but not on the Guides.

Editing the markdown content of the Test Types category to showcase it does not work yet.

Yes! @yasell, here the two issues I found:

1 - Welcome page is now broken.

2 - For consistency, the parent section option on the sidebar should be like the other sections.

• non-clickable
• non-bold style

Hey @ppcano! Fixed the welcome page and updated the parent section option on the sidebar, please review 🙏🏻

@yasell, the robots metatag seems not to be working.

See https://github.com/grafana/k6-docs/pull/1203/files#diff-bd57cb381d3607fe835978f4d267a4869c5893b10da4a65b9619f3ff7a87b692R4

and

The rest looks good. We can merge it after implementating/fixing this. And I am ok doing that change in another PR if that helps!
