Add "projectId" field to /evaluationForms - GetEvaluationsRequestDto

[perbergland]

Once a project matching the ATS project has been created for the first candidate in a project, we want to adapt the configuration possibilities to match the fact that most settings are now readonly.

We get this field already from ATSes like Teamtailor, Varbi, Visma, Talentadore etc - Talentech systems are the outliers ATM.

To accomplish this, we would like to add a nullable ProjectId string field to https://github.com/Talentech/EvaluationApi/blob/master/src/Dtos/Evaluations/GetEvaluationsRequestDto.cs, matching the ProjectId field in

EvaluationApi/src/Dtos/Invitations/ReferenceCheckInvitationDetailsDto.cs

Line 27 in 042486b

public string ProjectId { get; set; }

This needs to be matched by the same field in the private API used by the ATSes.

This is a backwards-compatible change and the ATSes can choose to start including it at their discretion at which time things will just get better for the users and less confusion in support calls.
