[Documentation] Add changes of recognizers-text utterances to the package description

[Aliandi]

Description

This PR adds a temporal description to the .csproj of Microsoft.Bot.Builder and Microsoft.Bot.Builder.Dialogs that includes the changes that come with the Recognizers-Text version upgrade.

Changes made

• Add description to Microsoft.Bot.Builder.csproj
• Add description to Microsoft.Bot.Builder.Dialogs

Result

This is what the preview looks like when the package is generated:

Note: This is a temporal solution, in the future the release note should be changed. If the NuGet team adds the option to add markdown, we would probably want to link the changes instead of writing them down. However, this will do for an initial version upgrade.

I think this is a good step towards informing users of the recognizers library upgrade.

However, this might now conflict with https://github.com/microsoft/botbuilder-dotnet/pull/2448/files which is also upgrading these same references.

Dismissing review because this PR should not be upgrading the recognizers references. (that is in 2448)

[cleemullins]

I don't think we want to do this.

This should go in the release notes, but I don't know if it should go here.

@cleemullins how about adding a link to the release notes here? And mention the recognizers upgrade, but without the details?
