Replace excel screenshots by embedded file contents

Fix #434.

This will also be hopefully more accessible for visitors using screenreaders since they can now more easily access the full information that was previously summarized in a terse alt text.

What does this mean?

If you have source files that require output and figures to be generated (e.g. R Markdown), then it is important to make sure the generated figures and output are reproducible. This output provides a way for you to inspect the output in a diff-friendly manner so that it's easy to see the changes that occur due to new software versions or randomisation.

I'm still unsure of what would be the best way to do this.

I went with saving only head() of the data. Alternatively, we could truncate the files before reading them with echo = FALSE to not distract the readers from the main point but I'm always wary of doing operations behind the scenes.
