[ fix ] Data and Type Constructor tags for :di

[stefan-hoeck]

Description

The :di command at the REPL confuses data and type constructors. Example:

CaseTree> :di Bool
Prelude.Basics.Bool
Type constructor:
  tag: 100
  arity: 0
  parameter positions: []
  constructors: Prelude.Basics.False, Prelude.Basics.True
Compiled: Data Constructor:
  arity: 0

As can be seen, Bool is listed as a "Data Constructor" in its compiled form. Likewise, True or False will be listed as type constructors. The fix is trivial.

Should this change go in the CHANGELOG?

• If this is a fix, user-facing change, a compiler change, or a new paper
  implementation, I have updated CHANGELOG_NEXT.md (and potentially also
  CONTRIBUTORS.md).
