Improve `--install`

`--install` option is an interesting feature. When you maintain a big project, it could significantly help you - for example, avoid loading to CI unnecessary heavy dependencies that are used only in some scripts. However, now this option has some significant issues.
- At this moment, this option install **all** dependencies of the script - even if this dependency is already installed at the root of the project.
- It's problematic to control versions of dependencies if they are defined as comments of imports - this dependency can be used in some different scripts, the actual tools for updates checking can't get access to versions from those comments.
- Dependencies from the monorepo (`workspaces`) also installed and resolved incorrectly.
- It's problematic to configure installing process.

- The first issue can be solved by checking the existence of the dependency in the top-level `node_modules` of the project before installing.
- The second can be solved by adding a way to define those versions in a `package.json` (top-level of the project or defined in another place) without installing those dependencies. In the case of the top-level `package.json`, it can be `optionalDependencies`.
