Docs: Clean up references to old settings/configs (marcoroth#943)

With the `.herb.yml` we combined the settings into a single
configuration file, which refactored away the `.herb-lsp/config.json`
and some of the VS Code-specific settings.

 ## Configuration
 
-The language server can be configured using a `.herb-lsp/config.json` file in your project root. This file is automatically created when the language server starts if it doesn't exist.
-
-### Formatter Configuration
+The language server can be configured using a `.herb.yml` file in your project root. This configuration is shared across all Herb tools including the linter, formatter, and language server.
 
-You can configure formatting behavior by adding a `formatter` section to your config:
+See the [Configuration documentation](https://herb-tools.dev/configuration) for full details.

-#### `formatter` Options
+```yaml
+# .herb.yml
+linter:
+  enabled: true
 
-- `enabled` (`boolean`): Enable or disable formatting for this project. Defaults to `false`.
-- `indentWidth` (`number`): Number of spaces for each indentation level. Defaults to `2`.
-- `maxLineLength` (`number`): Maximum line length before wrapping. Defaults to `80`.
+formatter:
+  enabled: true
+  indentWidth: 2
+  maxLineLength: 80
+```
 
-**Note**: VS Code users can also control formatting globally through the `languageServerHerb.formatter.enabled` setting in VS Code preferences. Formatting is currently in **Beta** and disabled by default.
+**Note**: VS Code users can also control settings through `languageServerHerb.*` settings in VS Code preferences. Project configuration in `.herb.yml` takes precedence over editor settings.

 ## Configuration
 
-### Linter Settings
+The extension can be configured through VS Code settings or a `.herb.yml` file in your project root. Project configuration in `.herb.yml` takes precedence over VS Code settings.
 
-You can configure the linter behavior through VS Code settings:
+See the [Configuration documentation](https://herb-tools.dev/configuration) for full details.
+
+### VS Code Settings
 
 * `languageServerHerb.linter.enabled` (boolean, default: `true`) - Enable/disable the linter
-* `languageServerHerb.linter.excludedRules` (string[], default: `["parser-no-errors"]`) - Array of linter rule names to exclude from diagnostics
+* `languageServerHerb.formatter.enabled` (boolean, default: `false`) - Enable/disable the formatter
 
 #### Example configuration in `settings.json`:
 
 ```json
 {
   "languageServerHerb.linter.enabled": true,
-  "languageServerHerb.linter.excludedRules": [
-    "parser-no-errors",
-    "html-tag-name-lowercase"
-  ]
+  "languageServerHerb.formatter.enabled": true
 }
 ```
 
-**Note:** The `parser-no-errors` rule is excluded by default to prevent duplicate error reporting, since parser errors are already displayed through the language server's built-in diagnostics.
