RSS feed contains relative images

For example, the https://www.tidyverse.org/blog/index.xml entry for the most recent blog post https://www.tidyverse.org/blog/2024/02/ggplot2-3-5-0-axes/ contains image references like:

<img src="figs/minor_ticks-1.png" alt="Scatterplot of engine displacement versus highway miles per gallon. Both the x and y axes have smaller ticks in between normal ticks." width="700px" style="display: block; margin: auto;" />

Note: I converted the ampersand codes from the raw XML to show the relative figure path more clearly.

This shows up as a broken image for some feed readers:
