Fix incorrect snippet description

Typo

Description

The example used for SqlCommand(String) has the following description:

"The following example creates a SqlCommand, passing in the connection string and command text."

The problem is the lack of a connection string in the example. How should the the connection string be provided in this example? I assume the proper description would be:

"The following example creates a SqlCommand, passing in the command text."
