Make node-sass optional in peerDependencies

[StetsenkoBohdan2002]

• Added peerDependenciesMeta section in package.json to mark node-sass as optional.
• This change allows users to install either node-sass or sass without warnings if node-sass is not present.
• Ensures greater flexibility for users who prefer using Dart Sass or other implementations.

I saw 2 small improvements:

1. increase the patch version of the package.
2. increase the Node version to one that supports NPM with peerDependenciesMeta.

See the pull request remarks for more details.

Hey I'm not the maintainer of this package, but I was also looking at creating a PR when I found yours.

TLDR: My suggestion is to also update the engine node version to at least 10.

Reasoning:

peerDependenciesMeta is a feature introduced in NPM 7, which was released with Node version 15.
If I take a look at the release notes from that time. NPM 7 only works with Node versions 10 and up:

https://docs.npmjs.com/cli/v7/using-npm/changelog#some-high-level-changes-and-improvements

So on line 29 I would also upgrade node "node": ">=4" towards at least "node": ">=10".

The patch version of the package should also be increased by 1:
line 3 : 3.0.0 -> 3.0.1

As 3.0.0 already exists as a NPM package:
