Request: Bump MEC and MEL to at least 2.2.0

[JustinGrote]

Hello,

PSES on Win5.1 loads 2.0.0.0 assembly of Microsoft.Extensions.Configuration. Most non-MS config extensions (YAML, TOML) require at least 2.2.0.0 so my PowerConfig module will not work when running in a PSES context on Win5.1 (works fine on 7 because it's abstracted into an ALC).

Any chance a bump to 2.2 would be possible?

@JustinGrote Do you know if it's guaranteed that these versions of these two libraries exist wherever PowerShell 5.1 exists? We don't explicitly declare either of these dependencies, but they are required by OmniSharp at 2.0.0.0, so if we were to update underneath it we would have to test for compatibility. Might I suggest opening an issue with OmniSharp to get them updated and tested for compatibility, and then we can update our OmniSharp dependency.

@andschwa the libraries aren't part of Powershell 5.1, they are loaded by PSES and because PSES in PS5.1 can't use AssemblyLoadContexts, they "pollute" the main runspace.

TBH the first part of my question was no longer relevant once we realized OmniSharp was bringing them along, sorry 🤷 I only just was able to make my coffee for the day.
