Bump Microsoft.Data.SqlClient from 6.1.3 to 6.1.4

[dependabot]

Updated Microsoft.Data.SqlClient from 6.1.3 to 6.1.4.

Release notes

Sourced from Microsoft.Data.SqlClient's releases.

6.1.4

This update brings the following changes since the 6.1.3 release:

Fixed

• Fixed NullReferenceException issue with SqlDataAdapter when processing batch scenarios where certain SQL RPC calls may not include system parameters.
  (#​3877)
• Fixed connection pooling issue where extra connection deactivation was causing active connection counts to go negative.
  (#​3776)

Added

AppContext Switch for enabling MultiSubnetFailover

What Changed:

• Added new AppContext switch Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault to set MultiSubnetFailover=true by default in connection string.
  (#​3851)

Who Benefits:

• Applications that need MultiSubnetFailover enabled globally without modifying connection strings.

Impact:

• Applications can now enable MultiSubnetFailover globally using one of the following methods:

// In application code
AppContext.SetSwitch("Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault", true);

// In runtimeconfig.json
{
  "configProperties": {
    "Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault": true
  }
}

<!-- In App.Config -->
<runtime>
  <AppContextSwitchOverrides value="Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault=true" />
</runtime>

Changed

• Optimized SqlStatistics execution timing by using Environment.TickCount instead of more expensive timing mechanisms.
