Fix whitespace in example documentation mkdocs.yml that breaks mkdocs
I've torn my hair out a number of times after copying and pasting this broken sample yml. Only just realised it is the source of my vexation.
Importantly: you need a space after toc:
and before true
, or you get errors like
ERROR - Config value: 'markdown_extensions'. Error: Invalid config options for Markdown Extension 'toc'.
