[bug] TAURI_FRONTEND_PATH and TAURI_APP_PATH have wrong semantics

[istudyatuni]

Describe the bug

I ran tauri init in gui folder and moved src-tauri folder to crates/tauri-app, and I should set variables to

export TAURI_FRONTEND_PATH="$(pwd)/crates/tauri-app"
export TAURI_APP_PATH="$(pwd)/gui"

for tauri-cli to work, but I think it should be opposite. I think fixing it would be a breaking change, so probably this could be mentioned somewhere

Reproduction

mkdir gui && cd gui
yarn create vite .
yarn add -D @tauri-apps/cli@latest
yarn tauri init
mv src-tauri ../crates/tauri-app

# swap
export TAURI_APP_PATH="../crates/tauri-app"
export TAURI_FRONTEND_PATH=.
yarn tauri dev

Expected behavior

App running

Couldn't recognize the `TAURI_FRONTEND_PATH` folder as a Tauri project. It must contain a `tauri.conf.json`, `tauri.conf.json5` or `Tauri.toml` file in any subfolder.
