Cannot install plugin from GitHub via https using startup.sh
### Describe The Bug

Hi,
i cannot install my plugin via https GitHub url using startup.sh.

I tried `npm install https://github.com/benzman81/homebridge-nukiio.git` leading to a permission error and `hb-service add https://github.com/benzman81/homebridge-nukiio.git` seems to be unsupported.

Even `npm install homebridge-nukiio` doesnt seem to work. Installation seems good, but homebridge tells me, that it does not find the plugin.

Only `hb-service add homebridge-nukiio` works as expected.

Until yesterday the command `pnpm install https://github.com/benzman81/homebridge-nukiio.git` worked, but I saw you changed back to npm, so I wanted to change, too.
