Suggestion: Fix doc to save-dev and not save

[fokolo]

Hi :)
As far as I understand this library is only for dev work therefore it should not be bundled in any production build no?

so in the doc instead of:

Installation
npm install --save kysely-migration-cli
If you prefer Yarn:
yarn add kysely-migration-cli

it should be

Installation
npm install --save kysely-migration-cli
If you prefer Yarn:
yarn add kysely-migration-cli
pnpm:
pnpm i -D kysely-migration-cli

Good job at the lightweight lib!

@fokolo Thank you for your interest in this project and the suggestion. I think it's up to users; some users want to install it as a production dependency to run migration to production DB, while others want to run them in a separate environment such as CI. I want to make the default unopionated, so the current doc sounds good.

Besides, your suggestion to include pnpm in the doc is great - if you create a PR for this, I'm happy to merge it.

yes, sometimes you want to perform this script on a production env.

A good example of that is when migrating latest changes on your automated deployment.

Closing as dev/non-dev policy is now clear and pnpm was added to readme.
