Describe the bug

Hi,

It seems Clion is not able to show previews of .MD documents (with the Markdown plugin installed).

I get this popup on Clion:
Please consider switching to the bundled Java runtime that is better suited for the IDE (you current Java runtime is 11.0.11 by Oracle Corporation at '/nix/store/8c75xbd21d6fjv33rjglpsaxn6l3n0s1-jetbrains-jdk-11_0_11-b1504.13/lib/openjdk/').

On the markdown plugin settings it says: "There are no available preview providers". A quick search on google reveals that the usual fix is to use the jdk bundled with clion. That said, it seems we are indeed using it? ( '/nix/store/8c75xbd21d6fjv33rjglpsaxn6l3n0s1-jetbrains-jdk-11_0_11-b1504.13/lib/openjdk/' )

Steps To Reproduce

Steps to reproduce the behavior:

1. Add jetbrains.clion via nix (I used unstable - 2021.2.3)
2. Add the markdown plugin on Clion
3. Open a .MD document - no preview available
