Feature : tutorials to pdf

[the-matrixneo]

I have tested the implementation locally by ensuring the generated prince-list.txt correctly populates with URIs for both documentation and tutorials. The logic supports the full nested structure of the tutorial sidebar.

Please review the merge request
Issue no: #468

Thank you for the contribution! This is useful.

In the PDF I built from this PR, tutorials start from page 443. In the table of contents, I don't see anything about the tutorials. Or should I look specifically somewhere?

Also, the Quickstart tutorial (only), appears to have larger font. I guess this is because it does not yet have a sidebar (intentionally, but maybe we can rethink that decision), but then this is a separate issue.

As a side effect of including the tutorials (which have many pictures), the resulting PDF is 17MB (compared to the previous 3-4MB). If you see any easy way to reduce the size, that would be great!

In any case, I would appreciate it if you could post screenshots of any updates, or share the PDF itself, as it is currently a bit cumbersome for me to build locally.

I will add tutorial_sidebar loop to tocpage.html (pg 443+)

To solve the size issue caused by tutorial pictures, I was confused a bit to either use an argument or to implement some variable technique.

docs: I believe we should explicitly list these optimization techniques in docs-meta-publish-to-pdf.md as this will serve as a guide for future work to ensure that the PDF remains lightweight.

@the-matrixneo hey! solid PR!

PS. minor suggestion regarding commit history. I think its better to use git rebase if trying to bring your feature branch upto date with the master branch. This keeps the commit history much much cleaner and pays in multiples later on. You could also git squash all the commits into a single commit.
