New tag @minItems 1

[samchon]

Until yesterday, prisma-markdown could not distinguish whether 1: N relationships are mandatory or not. In such reason, prisma-markdown had drawn 1: N relationship as ||---|{ symbol regardless of the N position is whether mandatory or optional.

To make it clear, I've come with new idea @minItems 1 tag. If the tag being written on a 1: N relationship accessor, prisma-markdown will draw ||---|{ symbol. Otherwise it does not exist, ||---o{ symbol would be drawn instead.

model bbs_articles {
    id String @id @db.Uuid
    created_at DateTime @db.Timestamptz
    deleted_at DateTime? @db.Timestamptz

    //----
    // RELATIONS
    //----
    /// @minItems 1
    snapshots bbs_article_snapshots[]
    comments                bbs_article_comments[]
}
