Peer dependency warning for `@csstools/css-syntax-patches-for-csstree`

[npetruzzelli]

v5.3.4 of cssstyle pins the version of @csstools/css-syntax-patches-for-csstree to 1.0.14
https://github.com/jsdom/cssstyle/blob/v5.3.4/package.json#L39-L46

Because of #256

But this has an unused peer dependency for postcss, which was the only fix in 1.0.15.

Can the pinned version be bumped up to 1.0.15?

We will do a new release with the current package.json (which has been unpinned) soon. Closing, since the main branch is already fixed.
