Hugo version is woefully out-of-date

[jeremy-jameson]

The website is currently built using Hugo 0.80.0 (released December 31, 2020).

I built the website using the latest version of Hugo (0.97.3) and compared the output with the previous version. There are a number differences:

• whitespace differences in <figure> elements (specifically, whitespace before the <img> and <figcaption> elements has been removed)
• in code blocks, tabindex="0" is added to the <pre> element
• additional <span> elements in code blocks (e.g. but any visual differences in the rendering of the code blocks are not noticeable)

These differences appear to be benign. Consequently, updating to the latest version of Hugo is recommended (to incorporate bug fixes and other improvements).
