Serializer groups on property no longer supported

[calls9-tylersmith]

API Platform version(s) affected: 3.1.6 (Schema-generator version 5.2.0)

Description

The groups parameter no longer generates Groups attribute for properties as stated in the documentation.

How to reproduce

The below config (excess removed) describes a referral resource that has one property person. A Person has one property email. The normalization context of the post collection endpoint for Referral has the serialization group set to "referral:post:write" (this works as expected). The email property on Person has the groups option set to referral:post:write such that a person entity can be created from the Referral collection post resource.

types:
  Referral:
    guessFrom: Referral
    properties:
      person: {range: Person, cardinality: (*..1)}
    operations:
      Get:
        normalizationContext:
          groups: [referral:item:read]
      GetCollection:
        normalizationContext:
          groups: [referral:collection:read]
      Post:
        denormalizationContext:
          groups: [referral:post:write]
        normalizationContext:
          groups: [referral:post:read]
  Person:
    properties:
      email:
        range: https://schema.org/Email
        required: true
        groups: 
          - referral:post:write

Outcome:
When generating this schema, the groups option on Person is ignored. Looking through the code, it looks like the option is defined, but never used. This functionality used to work in version 4.0.1 through ApiPlatform\SchemaGenerator\AttributeGenerator\SerializerGroupsAttributeGenerator. This functionality seems like it's no longer available, though it's still referenced in the documentation.
Possible Solution

It is possible to set the Groups attribute using the attributes option, but this is a workaround. In this case it would still be necessary to at least remove groups from the list of supported options in the documentation, and code.

Ideally the functionality would be added back into the current version.

Additional Context

[alanpoulain]

Indeed, groups has been replaced by attributes. Could you make a PR to update the documentation?

It is done by AttributeGenerator, however USE imports are missing in the generated classes. Can anybody fix it? Or should I create PR (Im using this generator for the first time, it might take the time).

EDIT: I was able to fix it using following configuration

uses:
    Groups:
        name: Symfony\Component\Serializer\Annotation\Groups
