[prettier-plugin-pkg] "pre" and "post" scripts

[sosoba]

Currently the plugin treats all scripts as independent and sorts them alphabetically. This does not well represent the idea of ​​npm where the prefix "before" and "after" have specific meanings. Ex.

"scripts": {
  "test": "node --test",
  "preversion" :"tsc && npm run test",
  "version": "npm publish",
  "postversion": "git push --tags"
}

has currently order that does not reflect reality:

"scripts": {
  "postversion": "git push --tags",
  "preversion" :"tsc && npm run test",
  "test": "node --test",
  "version": "npm publish"
}

I suggest to parameterizing this action.

I like this idea personally, PR welcome if you have time to contribute.
