also the markdoc config file has been updated

[ChristineTham]

It should build if you upgrade astro to 2.80 and @astrojs/markdoc to 0.4.1 (apparently the version numbers need to match between the two packages).

Or upgrade to the current latest of both.

I have updated the main branch so that it builds locally. However, I am running into this issue trying to deploy into Github Pages with the 'base' configuration parameter set.
