docs: drop GLFM specific math mode in favor of generic $ math mode
With CERN GitLab finally on >=15.7, we can drop the GLFM math mode and use the more common $ inline $
and
$$
block
$$
math modes. While I prefer the GLFM way, it's clear that the majority of Markdown interpreters doesn't support it (e.g. GitHub's). Switching also has the advantage that we can remove some of our code in our converter script, which should reduce the time to convert the docs to hugo format.
In total, we need to do three things:
-
Change all appearances of GLFM math modes and replace them with $ math modes -
Adapt the documentation on how to write equations in Markdown -
Remove unneeded code from converter script
Low priority issue though since our setup works just fine...
