Fix typo on TagType field

[carlosthe19916]

The current definition of the class TagType is something like:

@Entity
@Table(name = "tag_type")
@SQLDelete(sql = "UPDATE tag_type SET deleted = true WHERE id = ?", check = ResultCheckStyle.COUNT)
@Where(clause = "deleted = false")
public class TagType extends AbstractEntity {
   
    @Filterable
    public String colour;
   
}

Shouldn't the field colour should be named color?
The location of the field mentioned is this one:

It's written in UK English (rather than in US English) so it's not a typo 😉
