Okay, so I did rewatched "Rainforest Shmainforest" and it turns out that the girl with the black hair that was supposedly Heidi has her hair automatically change to her modern Dull Brown hair. I'm fairly certain it was an animation error, so I don't know if this yet confirms Heidi's debut. However, throughout the episode, the girl with the black hair that was supposedly Heidi had black hair the same shape as Heidi's, and when her hair turns Dull Brown in some scenes she looks exactly like Heidi, but without the hat obviously since she didn't wear it back then. So this might confirm her debut.

But still, even though the girl in the movie that was supposedly Heidi had black hair shaped like her modern Dull Brown hair (just like in "Rainforest Shmainforest"), I don't think it was actually her since she was shown wearing an orange shirt, and characters in the show are usually given trademark clothes and hair. Therefore, I don't think the movie was her first speaking role.

Since characters are given trademark clothes and hair, and I didn't find a single episode where a character mentions that Heidi got a hair dye (and obviously didn't one where they mention her new shirt since cartoon characters wear the same thing everyday, it's likely that her debut incident in "Rainforest Shmainforest" was just an animation error.

TL;DR: I'm still not sure about her debut. You decide whether "Rainforest Shmainforest" was her debut. Oh and if you go to the Images page for "Rainforest Shmainforest" I think in one of the inages you can see the girl that was supposedly Heidi.
