Print other enums for better understanding on 4.17.1 example.

Summary by CodeRabbit

• Documentation
  • Expanded the example to print string representations for three age groups instead of just one, improving clarity and demonstrating multiple outputs.
  • Updated sample output to reflect the additional print statements, helping readers understand expected behavior across different cases.

Poem

I tapped my paw, then printed three—
Children, Teens, and Grown-ups, whee!
Lines now hop in one-two-three,
A chorus of String()s in harmony.
Code nibble, doc dribble—happy bunny spree! 🐇✨

44-46: Prefer relying on fmt’s Stringer behavior (drop explicit .String())

fmt automatically calls the String() method for types that implement it. This keeps the example idiomatic and a bit cleaner.

Apply:

-fmt.Println(CHILDERN.String())
-	fmt.Println(ADOLESCENTS.String())
-	fmt.Println(ADULTS.String())
+fmt.Println(CHILDERN)
+  fmt.Println(ADOLESCENTS)
+  fmt.Println(ADULTS)

Note: If you want to keep explicit .String() for teaching purposes, feel free to ignore. Unrelated nit: “CHILDERN” seems misspelled; consider “CHILDREN” in a future pass for consistency.

45-46: Fix MD010 (no hard tabs) in code block

markdownlint flagged hard tabs on these lines; replace with spaces to satisfy CI/lint.

-	fmt.Println(ADOLESCENTS.String())
-	fmt.Println(ADULTS.String())
+  fmt.Println(ADOLESCENTS.String())
+  fmt.Println(ADULTS.String())

45-46: LGTM: additional prints improve example clarity

Showing all enum values helps readers understand String() across the full range.
