[WIP] Add Particle Argon, Boron and Xenon

[suda]

This PR adds Particle Argon, Boron and Xenon boards to the docs.

It's blocked by tinygo-org/tinygo#904 after which is merged, we can run make doc-gen to generate machine package docs for those boards.

Switched to dev branch so it gets picked up next release.

tinygo-org/tinygo#904 was merged, is anything besides the make doc-gen stopping this to be merged too?

[suda]

No, only make doc-gen is blocking. It's sill failing on particle-argon and I assumed it's because the tinygo-org/tinygo#904 got merged into dev branch and doc-gen expects master. Is there a way to force generating docs from the dev branch?

Is there a way to force generating docs from the dev branch?

If you have the dev version of TinyGo installed (go install) it should just work.

[suda]

Oh installing made it run! It's just generating an empty file, i.e.:

---
title: particle-argon
---

It actually resets all files in content/microcontrollers/machine. Anything else I might be missing?

[aykevl]

I'm not sure what goes on there, it works for me (and includes the Particle boards).

[suda]

Ok, I got it working! Ready for review 😊

Now merging, thanks @suda
