Accesstoken support for Frends.MicrosoftSQL

To support additional databases such as Microsoft Fabric and Azure SQL, it would be beneficial to add optional accesstoken to Frends.MicrosoftSQL -tasks. Such implementation has been done as a custom task, from base of Frends.Community.WindowsSQL -task (https://github.com/CommunityHiQ/Frends.Community.WindowsSQL/issues/7).
