calling from child_process results in exit code 7

[jdalton]

An example of running tsgo from a child_process

1. npm install -D @typescript/native-preview
2. touch .env
3. Run

   npx dotenvx -q run -- tsgo
   // => Command failed with exit code 7: /Users/jdalton/projects/try-it/node_modules/.bin/tsgo

   OR

   npx dotenvx -q run -- ./node_modules/.bin/tsgo
   // => Command failed with exit code 7: /Users/jdalton/projects/try-it/node_modules/.bin/tsgo

This is a duplicate of #906; error code 7 is "--incremental doesn't work".

Oh cool. Glad to know it's not a problem with subprocess stuff 😺

Don't error on --incremental, just run normally
