Fix/489 dynamic root alias

[ekraffmiller]

What this PR does / why we need it:

This PR removes the use of 'root' as a constant to refer to the alias of the root collection. Instead, it depends on js-dataverse to use the default root collection id, ':root' to get the root collection.

Which issue(s) this PR closes:

• Closes Support dynamic alias for the root collection #489

Special notes for your reviewer:

The logic for handling the loading state of the Collection in Account.tsx and LoggedInHeaderActions.tsx needs a closer review, I wasn't sure the best way to handle the isLoading state.

Suggestions on how to test this:

Step 1: Run the Development Environment

1. Execute npm i.
2. Navigate with cd packages/design-system && 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. In the SPA test that the Create Dataset and Create Collection features work from the root collection, and subcollections.
2. In JSF, login ad Dataverse Admin and. go to the root collection. Choose Edit -> General Information. In the edit form, change the Identifier from 'root' to another alias. Also change the Dataverse Name from 'Root' to something else.
3. In the SPA, from the HomePage click 'Browse Collections'. The new name and alias of the root collection should appear on the Collections page. Test that you can Create a Dataset and a Collection from this page.
4. From the Header, test that you Create a Dataset and a Collection.
5. Go to the Accounts Page check that the Breadcrumb has been removed from the page

I’ve tested this in my local environment and it works great! 🎉
Nice work @ekraffmiller, this is a very nice addition to the SPA!
I just left some minor improvements that could be done.
