[MINOR][DOCS] Remove generated statement about Scala version in docs homepage as Spark supports multiple versions

### What changes were proposed in this pull request?

Remove this statement from the docs homepage:
"For the Scala API, Spark 3.3.0 uses Scala 2.12. You will need to use a compatible Scala version (2.12.x)."

### Why are the changes needed?

It's misleading, as Spark supports 2.12 and 2.13.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

N/A

Closes #37381 from srowen/RemoveScalaStatement.
