feat: inject version into fast-element source

[EisenbergEffect]

🙋 Feature Request

The FASTGlobal has a versions array. Instances of fast-element should push their version number into the array if it is not already present. This will enable easy detection of multiple versions as well as which versions are loaded.

🤔 Expected Behavior

FAST.versions should return an array of loaded fast-element versions.

😯 Current Behavior

The array is empty.

💁 Possible Solution

This will need to be accomplished through a combination of a small amount of code added to fast-element along with beachball integration. Here is the relevant beachball issue:

🔦 Context

It would be nice to know what version or versions are loaded at runtime.

💻 Examples

console.log(FAST.versions); // ['2.0.0']

Would this ultimately help fix the instanceof check errors on FASTElement, or is there no way around that other than just making sure you're not loading multiple versions of the library?
