Add pretty code rendering feature

[clinssen]

Use for marketing/documentation purposes.

Do we need to merge the images as well? We can generate them whenever required by just running the script, right?

That's true, I thought it might help to show what the output would look like. Perhaps we should add this feature as a kind of mock "code generator" in the documentation, what do you think?

What do you mean by "mock code generator" here? We are not generating any code but rather rendering the model code in. a pretty format, correct?

Well, hypothetically we could add an extra code generation target platform which would do the pretty printing, akin to the model docs generator (autodoc). I'm not sure if it's the right thing to do or if it's going too far for such a simple feature.

I wouldn't go as far as to have a new code generator for this as this feature would be rarely used. I think just retaining the scripts and generating the images when required would be enough.

I have refactored the pretty rendering feature as a separate code generator.

The rendered version of the docs can be found here: https://nestml--1081.org.readthedocs.build/en/1081/running/index.html
