[CraigMacomber]

Description

Since SchemaFactoryAlpha seems to be sticking around for a while and its APIs are not getting stabilized to public on a short timeline, flesh out its overrides to be a bit more complete and consistent.

Pull Request Overview

This PR fleshes out SchemaFactoryAlpha by adding non‐static (instance) overrides for several schema helper properties and updates the alpha API reports and changeset accordingly.

• Expose instance overrides for leaves, optional, required, optionalRecursive, and requiredRecursive in SchemaFactoryAlpha.
• Update the generated .api.md files to include the new instance members and adjust system table schema entries to use FieldSchemaAlpha.
• Add an alpha override for requiredRecursive in both static and instance contexts and document it in the changeset.

• New instance override properties (leaves, optional, required, optionalRecursive, requiredRecursive) don’t appear to have accompanying unit tests. Consider adding tests to verify these instance members exist and match the static implementations.

public override readonly leaves = schemaStatics.leaves;

.changeset/whole-days-argue.md:6

• [nitpick] Consider clarifying this change description by replacing “overrides for more instance properties” with something like “instance overrides” to make it clearer that the PR adds non-static versions of several SchemaFactoryAlpha members.

Add overrides for more instance properties in SchemaFactoryAlpha

Left a docs suggestion, but otherwise this looks good to me!
