Remove label and placeholder from context and form, add optional provideDefaultLabelFromFieldName property to bridges.

[Monteth]

Changes are described here: https://github.com/vazco/uniforms/issues/973#issuecomment-1235430047.

This version doesn't include the provideDefaultLabelFromFieldName bridge property in SimpleSchema, since it always delivers a 'label' property. We cannot distinguish whether it was inferred from the field name or entered manually into the schema.

I run into a problem implementing the provideDefaultLabelFromFieldName functionality in SimpleSchema, you can follow the issue here: https://github.com/longshotlabs/simpl-schema/issues/480

[Monteth]

As I understand, as soon as we migrate to Zod in tests or Simple Schema solves the issue with the labels, we could remove all of these label: '' from tests?

Correct. Since we get rid of label in context, we can no longer tell SimpleSchema not to derive the label from the field name, so we have to pass it explicitly. This behavior is specific to SimpleSchema only.
