Allow user to access their own DOB

[maxidragon]

@danieljames-dj discovered that users cannot access their own DOB because it is restricted to WRT only. As a result, we (WRT) have received some empty forms, which were not actually empty. Users had entered the correct DOB, but after backend comparison, it was determined that there was no change, leading to an empty email notification.

In this PR, I've allowed users to access their own private_attributes, so their DOB will be prefilled in the edit profile form.

Thanks @maxidragon. I agree with the changes. But since this is having changes in sensitive information, I prefer to get approval from @gregorbg.

Also, question that I genuinely don't know the answer to:
Should users see their own incorrect_wca_id_claim_count? Because with this PR, they would. But I'm honestly not sure if that's a good thing.

Great catch. There is nothing wrong in providing, but it's currently not necessary. Maybe can we add just DOB for self users? WDYT @maxidragon?

Yeah, it's not necessary, I'll modify the code to add just DOB for normal users

@maxidragon Can I request for one more ask? Can you show the DOB for delegates as well? Delegate's edit profile form is also not populating the DOB.

Yep, changed

(Had to merge main again to get rid of a very weird CI quirk. Nothing wrong with your code!)
