Suggestions: package maintenance improvements

[marcalexiei]

Follow up to #140

[!NOTE] I'm creating a separate issue since the following changes should not affect package behaviour in user land.

[!NOTE] Alike #140 If you are ok with at least one of the proposed changes I can take care of doing separate PR's 😁

Linter

eslint is installed in devDependencies but it is not used in npm scripts or in actions as far as I can tell. It would be good to use the default configuration combined with https://typescript-eslint.io plugin

Formatter

Alongside with linting it would be good to have also a formatter. prettier is widely adopted so I would go for it, alternatively there is biomejs.

Unit test using snapshots

Add more check to GitHub actions

• Add checks for all supported node version
• Add lint and format checks too

Add commit message linter

In order to ease changelog maintenance (https://github.com/elycruz/rollup-plugin-sass/issues/118), commits should follow conventional commits. Having a commit linter + a git hooks manager will enable commit message validation on user commit:

Examples:

• Linter: https://commitlint.js.org
• git hooks manager: https://typicode.github.io/husky/
