Comment blocks are broken

[Akryum]

GraphQL comments syntax has changed and is now using a triple double-quotes characters format. This breaks syntax highlighting on GitHub.

Example on GitHub: https://gist.github.com/Akryum/74471ad4789e4fcde6e072ea0605c62b

This is still an issue and seems to not only be broken on github, but within the IDE itself as well, over a year over the initial report, I guess this isn't a very well maintained plugin.
