GitHub Action not loading gdal-config

[superjai]

Hey @bbest - the GitHub Action you created for infographiqR is not working properly. In particular, RMarkdown is not properly loading gdal-config when attempting to render Introduction.Rmd. Here is the relevant section of the log from the latest attempt to run the GitHub Action.

* installing *source* package ‘sf’ ...
** package ‘sf’ successfully unpacked and MD5 sums checked
** using staged installation
