getCustomPragmaVal Error: typedesc not allowed as tuple field.

[geekrelief]

In nim 1.6.0:

import macros

type
  foo = object

template typ(T:typedesc) {.pragma.}

proc bar() {.typ: foo.} = discard

static:
  echo bar.getCustomPragmaVal(typ)

Fails to compile with: Error: typedesc not allowed as tuple field.

Should be fixed by #19021
