AdaptiveCards.Templating 1.4.0

Issue

The June 2023 version of the Bot Framework (https://github.com/microsoft/botbuilder-dotnet/releases/tag/4.20.0) has changed to use ANTLR 4.11.1
See microsoft/botbuilder-dotnet#6558 and microsoft/botbuilder-dotnet#6586

AdaptiveCards.Templating is using ANTLR 4.8

Unfortunately ANTLR 4.10 (https://github.com/antlr/antlr4/releases/tag/4.10) seems to have broken the generated parsers and lexers in AdaptiveCards.Templating.

When creating a new AdaptiveCardTemplate class
new AdaptiveCardTemplate(templateJson).Expand(rootData)

we get a Type Initialization error
Method not found: 'Antlr4.Runtime.Atn.ATN Antlr4.Runtime.Atn.ATNDeserializer.Deserialize(Char[])'.

This incompatibility is very annoying! Is there any ETA on this?
