Upgrade Scio to 0.14.12; run CI on Java 17; use magnolify-bigquery in BigDiffy

[clairemcginty]

• Upgrades Scio to 0.14.12, which unblocks Java 17+
• Updates CI to run on Java 17 (thus the added JavaOptions.scala file, which adds options required for 17+). Note that the project still has the -target 8 scalaOpt so it will continue to produce Java8-compatible bytecode
• Replaces BigQueryType usage in BigDiffy with magnolify-bigquery. BigQueryType is deprecated and less performant than Magnolify for BQ writes

Testing: Packaged locally and tested BigDiffy with BQ output to validate that all three tables (_fields, _global, and _keys) are produced correctly.

thanks @clairemcginty! I tested your changes with BigSampler and BigDiffy. Both succeeded, and the changes look good to me. TY!
