Support for pnpm #3
Description
I wanted to add release-it to a repo which uses pnpm instead of npm, but it fails because at the end of the script it is hardcoded to do npm install --save-dev release-it.
Could this be made configurable so it could be pnpm add --save-dev? Or auto detect it the same way the github or gitlab remote repo is detected? I'm happy to make a PR if I get some indication wether this is something which you want implemented.
