docs: fiducial markers guide

[MithraGhlm]

Description

Initial draft of documentation for camera frame calibration guide.
This PR closes the camera frame calibration guide #479

This PR solves the issue by adding two stand-alone guides to the documentation.
The guide for intrinsic camera calibration already exists.
One guide is about the configuration and the process of recognizing STag marker (WIP) and a second one would be dedicated to calibrating the robot.

Thanks! First quick review:

@SprGrf Thanks

[MithraGhlm]

Should there be a stand alone guide to introduce the Robot Camera Calibration component?
Or is it better to have it in the same docs page?

Nice! The backbone is here, some first comments I had while reading:

[MithraGhlm]

In order to proceed here, please

2. Remove the hand-eye-calibration guide from this PR. We'll make a separate PR for it.

Before I change anything there, do you want the existing review comments be preserved or is it acceptable to move it to a new branch and create a fresh PR?

This is what I want to do: (Since the name of this PR is already HE calibration, I'll move the Fiducial Markers to a new PR)

1. Make a new branch for Fiducial Markers
2. Delete the fiducial-markers.md file and all media related to it

So the existing PR would be only for HE calibration.

Then I'll open a new PR for the Fiducial Markers and rebase on main.

Is this workflow accepted?

Unless we have actual guidelines how we want to improve style and formatting, there is no need increasing the scope of this PR to files that are unrelated to hand-eye calibration. It's good practice to keep scopes of PRs narrow.

I'm not against the changes alltogether, but this is not the place to do it. A reformatting PR would be more appropriate

As you correctly commented once on the #485 (This PR contains all commits from #482, could you untangle this?), I untangled #482 from #485.
The initial problem was due to me forgetting to switch to main before making the new branch. But then I rebased it on the main and the problem was resolved. Now #482 and #485 are 2 different PRs.

So I don't understand what you mean by: increasing the scope of this PR to files that are unrelated to hand-eye calibration. It's good practice to keep scopes of PRs narrow.

Since we don't have any specific guidelines yet, how about just merging the small changes and closing #485, instead of reverting it?

All 4 of my previous review comments are still unresolved

Just two last formatting nitpicks. Otherwise all good!

[domire8]

Alright looks good now! Good work with this 👍

[SprGrf]

Nice work, sorry it took me so long to return to this!
