[Telephony] Alphanumeric Input code only supports English disambiguation

[stevengum]

Describe the bug

    This is too fragile, and only works for English.

if (tokens[1].ToLowerInvariant() == "as" && tokens[2].ToLowerInvariant() == "in")

The SerialNumberInput node which supports alphanumeric input aggregation only supports English (e.g. listening for "as" or "in" and only supporting disambiguating '8' and 'A' at this time)

botframework-components/packages/Telephony/Actions/SerialNumberPattern.cs

Lines 15 to 18 in 66ab008

	private static readonly Dictionary<char, char> AlphabetReplacementsTable = new Dictionary<char, char>
	{
	{ '8', 'A' }
	};

Version

latest of Microsoft.Bot.Components.Telephony

Expected behavior

More languages than just English are supported or configurable by bot authors
