[pdflatex] Enable book style build of PDF via LaTeX

[mmcky]

This PR brings book style PDF support via LaTeX

@AakashGfude this doesn't seem to be picking up that there is a pdf available. How is the name of the file determined? I suspect i also need to update _config.yml

[mmcky]

This is presenting a settings button for the live build launcher. With one option it should just retain the single launch button. I think maybe my _config isn't setup correctly on this either?

Right @mmcky, we need to put only one launcher in _config. at present it has all of them https://github.com/QuantEcon/lecture-python-programming.myst/blob/master/lectures/_config.yml#L31

It gets the name from the latex_documents key.
The reason it is not detecting here is that I am checking for the presence of pdf before showing it. SInce latex is run after HTML in the ci. When building HTML, pdf is not present.
What I did earlier in the test PR was to move the latex build before HTML. https://github.com/QuantEcon/lecture-python.myst/pull/127/files#diff-b803fcb7f17ed9235f1e5cb1fcd2f5d3b2838429d4368ae4c57ce4436577f03fR31

Hmm one interesting issue is the cache that I have on github actions. We may need a mechanism to rebuild clean

thanks @AakashGfude this is looking nice. Could you take a look and let me know what you think.
