Which issue(s) this PR closes:

• Closes Collection Page: add Sort Button #561

Special notes for your reviewer:

In the Story and the ItemsSortBy component test, the style is not being applied to the selected option, even though it works in the app and in the CollectionItemsPanel Story.

Suggestions on how to test this:

Step 1: Run the Development Environment

1. Execute npm i.
2. Navigate with cd packages/design-system && npm i && npm run build.
3. Return with cd ../../.
4. Ensure you have a .env file similar to .env.example, with the variable VITE_DATAVERSE_BACKEND_URL=http://localhost:8000.
5. Navigate with cd dev-env.
6. Start the environment using ./run-env.sh unstable.
7. To verify the environment, visit http://localhost:8000 and check your local Dataverse installation.

Step 2: Test the feature

1. Create some collections and datasets in the root collection. Add one or multiple files in one of those created datasets.
2. When first navigating to http://localhost:8000/spa/collections, check that the Sort button has ' Newest' highlighted, and the 'Relevance' sort option doesn't exist.
3. Choose another sorting option. Check that the url is updated with the correct sort parameters.
4. Submit a search. Check that the sort button now has 'Relevance' highlighted, and the url only has the 'q=searchtext' param.
5. Choose another sorting option. Check that 'Relevance' is still visible, but not highlighted. Check that the items are sorted in the correct order.
