Ability to filter count in "Count Relation Feature"

Problem

Currently count relation feature just accepts true or false values and count all the related records. Sometimes we just need to count some of the records depends on the query.

For example

this.prisma.groupExamAttempt.findMany({
  where: {
    groupId: param.groupId,
    examId: param.examId,
  },
  include: {
    _count: {
      select: {
        answers: true,
      },
    },
  },
});

This will just passively count all the records there.

Suggested solution

To filter maybe we can add a where clause

this.prisma.groupExamAttempt.findMany({
  where: {
    groupId: param.groupId,
    examId: param.examId,
  },
  include: {
    _count: {
      select: {
        answers: {
          where: {
            isCorrect: true,
          },
        },
      },
    },
  },
});

Maybe if applicable, It can also be based on the deeper relationship filter. (IF ONLY THIS IS DOABLE)

Running into a need for this too. Would love to be able to do something like e.g. find users with >50 followers

prisma.user.findMany({ where: { followers: { _count: { gt: 50 } } } });

This is also pretty essential for soft deletes. Ex. no reason for deleted records to be included in the count.
