Update application name ODBC parameter

[jtcohen6]

My bad for directing us to the wrong docs in #63. Instead of APP we want Application Name. From Synapse PM:

On the application name parameter, for ODBC, please use “Application Name=dbt-{credentials.type}” (per your example). The key here is the parameter being “Application Name” with a space between Application and Name. If you happen to use JDBC, then you can use applicationName (no space).

While we're here, I figure it can't hurt to send the dbt-sqlserver version as well.

thanks @jtcohen6! two qqs:

• If I want to include this change as part of dbt-synapse v0.19.0, does that mean we should cut a new release of dbt-sqlserver?
• if so, what version should that be? I'm hesitant to go with v0.19.1 bc it'll likely be a dbt-core version we might need to support. Maybe v0.19.0.1? But, IIRC, any addition after the patch number makes PyPI think it is a pre-release.

Yes to a new release, and I think v0.19.0.1 is the right way to go! We released dbt-spark==0.18.1.1 when we needed a small fix, but still wanted to indicate version parity with dbt-core==0.18.1. I believe that PyPi/pip treat a version as pre-release IFF its suffix is dev, a, b, or rc (docs).
