Move postcss to devDependencies in "css-syntax-patches-for-csstree"

[jnoordsij]

When installing this package as nested dependency of cssstyle with Yarn PnP on the latest Yarn version (4.10.3), one is presented with the following error:

➤ YN0086: │ Some peer dependencies are incorrectly met by dependencies; run yarn explain peer-requirements for details.

which when inspected can be traced to

pb97ead → ✘ cssstyle@npm:5.3.1 doesn't provide postcss to @csstools/css-syntax-patches-for-csstree@npm:1.0.14 [bb38a]

Given that seemingly this package does not interact with postcss when inspecting the code, apart from in a single e2e test, I think moving it to be a dev dependency is more accurate.
