Documentation about reflect-metadata is now misleading

[terrybondy]

The documentation at https://github.com/inversify/InversifyJS/blob/master/wiki/environment.md contains the following note:

⚠️ The reflect-metadata polyfill should be imported only once in your entire application because the Reflect object is mean to be a global singleton. More details about this can be found here.

Related issues in the dependency:
#80 - metadata seemingly erased when using multiple files with karma,mocha,webpack
#78 - Error when working with another polyfill, like core-js/reflect
#45 - When installed redundantly, Metadata could be erased

seem to have been fixed (https://github.com/rbuckton/reflect-metadata/releases/tag/v0.1.12) in a previously used version of the dependency.

Expected Behavior

No note required.

Current Behavior

Has note.

Possible Solution

Can't agree more. The newest version of reflect-metadata, which has been released for more than 4 year, can be imported more than once.
