Added FluentUI Slider to chat settings panel for overriding temperature

[bscheurm]

Purpose

• The Chat Settings panel does not provide a way to override the temperature value for requests to the Azure OpenAI completion endpoint. This PR adds a slider to the panel for customizing the temperature. Note that no other changes are required other than UI because the existing code already supports a temperature override value, and the various approaches (located in app/backend/approaches/*) already use it.
