.Net: Upgrade MongoDB connector dependency to MongoDB.Driver to v3.x

[acorbin-vdm]

Hello,

I would like to suggest to you to upgrade the Microsoft.SemanticKernel.Connectors.MongoDB connector to v3.x.x.
Currently, the library dep for MongoDB.Driver is using v2.30 by default.
Since last year, MongoDB .NET driver has a breaking changes bumping to v3. There is no MongoDB.Driver.Core package, it has been removed and deprecated.

While using the nuget package Microsoft.SemanticKernel.Connectors.MongoDB with a solution which using the MongoDB.Driver v3, the method SaveReferenceAsync() throw an exception due to missing library.

Reference csproj MongoDB versions:

That's really locking for up to date projects, because we cannot use the package with recent MongoDB databases and/or driver.

Thanks a lot in advance,
Adrien
