[BUG] jquery-contextmenu is not loaded properly

[AbhinavBehal]

Describe the bug
The jquery-contextmenu npm package is not being loaded correctly, leading to an error being printed to the console:

index.html:106 Uncaught TypeError: $.contextMenu is not a function

To reproduce
Steps to reproduce the behavior:

1. Open the application
2. Observe that the above error appears in the console (Ctrl + Shift + I)

Expected behavior / Acceptance criteria

• This error should not be thrown
• The jquery-contextmenu package should be loaded correctly in the application

Desktop

• OS: Windows 10 - but I don't think this is an OS-specific issue

Additional context

• Look at this page to understand what the package does.
• This package is used to add a custom right-click menu to the network graph, as well as the component that lets you view file modifications.

I am getting the same error in console. Approved

Approved.

[swimuel]

I'm not seeing this error in console, could this be related to #196 where our jQuery version was updated?

[lukethompsxn]

I'm running the latest master and I'm still getting it on macOS (unlikely system dependent though)

[joel-clarke]

Yup, I'm still getting this as well on Windows.
