Support standard OIDC birthdate claim

[alex-swift]

OpenID Connect Core defines the list of the standard claims https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims. One of these claims is birthdate.

StandardClaims structure supports birthday, but does not support birthdate:
@see

openidconnect-rs/src/claims.rs

Line 107 in 1bc4a2f

pub(crate) birthday: Option<EndUserBirthday>,

Could you please add support for birthdate claim or rename birthday by birthdate?

ah shoot this looks like a typo. nice catch!

to avoid introducing a breaking change in case anyone depends on birthday, I think we'll need to add birthdate (of existing type EndUserBirthday) rather than rename birthday. I'm not sure when I'll have time to do this, but I would be happy to merge a PR that does this (with test coverage that adds the field to existing tests).
