Issue:
[Feature]: Emit diagnostics for ranges instead of single positions
### What problem does this feature solve?

Unlike other linter integrations, we only display diagnostics for a single position. This makes for a confusing and less useful experience for users.

### How does this feature solve the problem?

We should emit diagnostics for ranges that better describe the location of problems.

### What are some alternatives to this feature?

_No response_

 - Language server can now be restarted with the "Restart Stylelint Server" command ([#339](https://github.com/stylelint/vscode-stylelint/pull/339)).
 - The warning shown for unsupported versions of Stylelint will now be shown in any workspace with a locally installed copy of Stylelint, regardless of the file type of the open file ([#340](https://github.com/stylelint/vscode-stylelint/pull/340)).
 - Language server can now be disposed with `server.dispose()` and is disposed when receiving the shutdown LSP notification ([#326](https://github.com/stylelint/vscode-stylelint/pull/326)).
+- Add support for range warnings ([#358](https://github.com/stylelint/vscode-stylelint/pull/358)).
