fix: use Stencil watchers instead of global attributes util

packages/calcite-components/conventions/README.md

@@ -366,45 +366,7 @@ There are utilities for common workflows in [`src/utils`](../src/utils).
 
 ### Global attributes
 
-The [`globalAttributes`](../src/utils/globalAttributes.ts) util was specifically made to access the `lang` global attribute when set on a Calcite component. However, it can be extended to allow additional [global attributes](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes#list_of_global_attributes) by adding to the [`allowedGlobalAttributes`](https://github.com/Esri/calcite-design-system/blob/a33aa0df0c5bf103f91187826e6b12b8ff266d90/src/utils/globalAttributes.ts#L4-L5) array. The util is used in [`calcite-pagination`](../src/components/pagination/pagination.tsx), which you can use as a reference.
-
-#### Usage steps
-
-1. Import the interface and watch/unwatch methods
-
-   ```js
-   import { GlobalAttrComponent, watchGlobalAttributes, unwatchGlobalAttributes } from "../../utils/globalAttributes";
-   ```
-
-2. Implement the interface
-
-   ```js
-   export class ComponentName implements GlobalAttrComponent {
-   ```
-
-3. Add `globalAttributes` state
-
-   ```js
-   @State() globalAttributes = {};
-   ```
-
-4. Add connect/disconnect callbacks
-
-   ```js
-   connectedCallback(): void {
-       watchGlobalAttributes(this, ["lang"]);
-   }
-
-   disconnectedCallback(): void {
-       unwatchGlobalAttributes(this);
-   }
-   ```
-
-5. Use the state to access `lang` (or another global attribute that may be allowed in the future).
-
-   ```js
-   const lang = this.globalAttributes["lang"] || document.documentElement.lang || "en";
-   ```
+Watching global attributes on components is now possible with Stencil v4. Please refer to the [documentation page](https://stenciljs.com/docs/reactive-data#watching-native-html-attributes) for more information.
