Azure Ai Text Analytics Readme Issue

[v-jiaodi]

Section link:

Reason:
The TextAnalyticsApiKeyCredential is not in the @azure/ai-text-analytics .

Suggestion:
Update to:

const { TextAnalyticsClient, AzureKeyCredential } = require("@azure/ai-text-analytics");
const client = new TextAnalyticsClient(
  "<endpoint>",
  new AzureKeyCredential("<API key>")
);

@jongio for notification.
