Matches Scala version of Spark 3.4: https://github.com/apache/spark/blob/59fcecb5a59df54ecb3c675d4f3722fc72c1466e/pom.xml#L171

https://github.com/scala/scala/releases/tag/v2.12.16
https://github.com/scala/scala/releases/tag/v2.12.17

https://github.com/scala/scala/releases/tag/v2.13.6
https://github.com/scala/scala/releases/tag/v2.13.7
https://github.com/scala/scala/releases/tag/v2.13.8

Fix delta-io#1909

Changes Scala version, which should be compatible:
"As usual for our minor releases, Scala 2.12.17 is binary-compatible with the whole Scala 2.12 series."
"As usual for our minor releases, Scala 2.13.8 is binary-compatible with the whole Scala 2.13 series."

Closes delta-io#1936
