Add lerna exec

I’m submitting a Feature request

Motivation / Use Case

lerna exec makes it easy to run a command in every package in a repo. lerna run can cover most cases, but if we want to run a simple command like rm -rf ./lib in every package, or a subset of packages with --scope, it would be easier to migrate from Lerna if lerna exec was also part of lerna-lite.

Expected Behavior

Same behavior as Lerna’s lerna exec "my-command"

I don’t see the need to add exec when the only thing you would need to do is add an npm script in each package and use Lerna-Lite run. but anyway I wouldn’t oppose to receiving a PR for it (it would have to optional like run is), but just don’t expect me to do it since I really don’t see the need.

This is necessary in monorepo context, you cannot add scripts in each package this way, it’s too hard to maintain. For instance I use that for “depcheck”: https://github.com/VulcanJS/vulcan-npm/blob/main/package.json I’ve requested this feature in Turborepo as well: https://github.com/vercel/turborepo/discussions/375

Many thanks for releasing this feature, it works just perfect, with all arguments!
