Prettier 3.0.0 peer dependency compatibility issue

[annaghi]

Describe the bug
When installing the latest version of prettier-plugin-svelte with the latest version of Prettier (3.0.0), npm throws an error due to the peerDependencies of prettier in the package.json file. The peerDependencies are currently specified as ^1.16.4 || ^2.0.0, which doesn't cover Prettier 3.0.0.

To Reproduce
Steps to reproduce the behavior:

1. Use a project with the latest version of prettier (3.0.0).
2. Install prettier-plugin-svelte version 2.10.1.
3. Run npm i to install the dependencies.
4. See error:

Expected behavior
prettier-plugin-svelte should install without errors when the latest version of Prettier is used.

Suggested Solution
It might be sufficient to update the peerDependencies to include ^3.0.0 for prettier. However, I'm not sure if this is as simple as changing the version number in peerDependencies or if additional testing with Prettier 3.0.0 is needed to ensure compatibility.

Thank you for your attention to this matter!

This plugin is incompatible with Prettier 3 for now because of the breaking changes around the plugin interface, so the the information in peerDeps is actually correct. 🙂

Thank you for the prompt response, and I apologize for not having checked the PRs earlier.
I appreciate your work on this plugin!
