fix(create-robo): sometimes .gitignore isn't generated

Don't spend too much time on this if you can't replicate it.

Basically, there's a chance that the .gitignore file is not copied over when running create-robo and I have no idea why. I just ran into this when creating the robo-server project in the plugin-api benchmarks. However, attempting to do the same afterwards showed the .gitignore being generated correctly every time.

The options chosen were:

1. TypeScript
2. ESLint, Prettier, API Plugin
3. Skip

I've tried different combinations as well to no avail. I have a gut feeling that the TypeScript is affecting this somehow for some reason, probably because that decides which template directory is copied. Either that, or the package manager being used. (most likely PNPM)

This is not the first time it has happened either, others in our Discord server have reported this happening to them in the past.

It may help to work on this alongside #163 as that will give you several combinations and find the cause.
