[7.x][ML] Regression dependent variable must be numeric (#46072) (#46136)
* [ML] Regression dependent variable must be numeric

This adds a validation that the dependent variable of a regression
analysis must be numeric.

* Address review comments and fix some problems

In addition to addressing the review comments, this
commit fixes a few issues I found during testing.

In particular:

- if there were mappings for required fields but they were
not included we were not reporting the error
- if explicitly included fields had unsupported types we were
not reporting the error

Unfortunately, I couldn't get those fixed without refactoring
the code in `ExtractedFieldsDetector`.
