Support Stylelint 15

[fregante]

Tentative PR to support the new version. I don't know if anything else is necessary

I think that the issue isn't even here, actually 🤔 😅 I still haven't figured out how to read that wall of text in npm 8

This is needed here though https://github.com/hudochenkov/stylelint-order/releases/tag/6.0.2

Node 18 is already LTS: https://nodejs.org/en

In a separate breaking change, it might be worth dropping the rules, setting a stylelint v15 minimum, and adding prettier:

• Replace stylistic rules with prettier plugin #16

But 16 is also still LTS, and I generally prefer to support all active LTS versions.
