Automate examples directory creation on merge/commit

[cab-1729]

examples directory contains a compiled document for every single template hosted in this repository using this this document as input.
Build command is:

pandoc --verbose --pdf-engine=xelatex --template={}.tex -f markdown+inline_code_attributes+implicit_header_references+footnotes+definition_lists -t pdf Github\ Markdown.md > examples/{}.pdf

I would like to be able to automate building of all examples using Github workflows instead of compiling and committing the examples manually.
