feat: Implement Mdx

[dfireBird]

I ported mostly every thing to support Mdx plugin.

There is unresolved issues: When I try to add plugin (gatsby-remark-auto-headers-improved) to Mdx plugin it throws a load of errors. It's most probably an upstream bug I need more information to open an issues on the repo.

Edit: Installing the plugin with npm and using it Mdx plugins works.

Thank you so much! The failing build is my fault, the master branch build is currently failing, so I need to resolve that first!

[dfireBird]

I generated graphQL types just by providing a sample .graphql (since there are no .graphql files) is that the correct way?

[dfireBird]

There is discussion going on in this issue about module not found when using local plugins.

I did not give up on this :D sorry! I'm waiting and hoping for the issue with the local plugin, sadly gatsby-remark-auto-headers-improved is super key... I might need to create a npm package if it's not resolved

[dfireBird]

Thanks for explaining it! I thought you put this out for some other reason lol.

Edit: Why did you chose not to convert it a npm package?

[veksen]

I've externalized the library to npm https://github.com/the-programmers-hangout/website/pull/311

It's still possible that it doesn't play ball well due to the way the library interacts with Remark, I have to look at that, if so

[dfireBird]

I need to add the gatsby-remark-auto-headers-improved in both plugins option and gatsbyRemarkPlugins option because of this issue

[veksen]

I'm going to test it today and see if we can finally merge it. Does everything seem stable from your side?

Thank you again for handling this!

[dfireBird]

Everything seem stable on my side.
