New gender model

[Elblinator]

The client and the backend have a new model for the genders
it appears that the autoupdate needs to implement the new collection.

       The autoupdate service gives following:

Error: getting next message: creating first time data: create keys for
keysbuilder: load needed keys: restricting data: getting restiction mode for
gender/A: collection "gender" is not implemented, maybe run go generate ./...
to fetch all fields from the models.yml

I suppose that the autoupdate service needs to implement the new 'gender' collection in the restrictor.
Running go generate doesn't help-

The new gender:

• The Gender stays optional for the user (you are allowed to give no gender at all)
• the four base genders (male, female, diverse, non-binary) are the default genders
• the default genders cannot be deleted
• new additional genders can be created
• The name of new genders can be changed and they can be deleted
• genders are now called via the gender_ids

Please look into the changed in models.yml and the action in the respective PRs

I created a PR

When should a user see the gender collection? For the start, I set it to always. So every buddy, even anonymous, can see all genders.
