Integrate get application terms of use in account linking

[g-saracca]

What this PR does / why we need it:

Integrate the js-dataverse GetApplicationTermsOfUse use case.
After a successful OIDC login from the SPA, an account linking / complete information screen is displayed. At that point, we need to display the Installation Terms Of Use.

Which issue(s) this PR closes:

• Closes Show Application Terms of Use in Account - Sign Up page. #674

Special notes for your reviewer:

⚠️ The js-dataverse package is using a PR version, after IQSS/dataverse-client-javascript#296 is merged we need to update package version to use alpha.

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
5. Navigate with cd dev-env.
6. Before running next step, be sure have a fresh unstable dataverse image.
7. Start the environment using ./run-env.sh unstable.
8. To verify the environment, visit http://localhost:8000/ and check your local Dataverse installation.

Step 2: Test the feature

1. Got to the SPA and click the Log In button.
2. Sign in with a user from the keycloak instance
   email: dataverse-user@mailinator.com
   pass: user
3. You should be redirected to the Account - Sign Up page. Under General Terms of Use you should see the default message when installation terms of use are not set which is "There are no Terms of Use for this Dataverse Installation". Don't close this page.
4. Now lets update the applications terms:

• Create a tou.html file in your desktop with something like: <p>Be nice to each other</p>
• now run curl -X PUT http://localhost:8000/api/admin/settings/:ApplicationTermsOfUse --upload-file ~/Desktop/tou.html and you should receive a response like: {"status":"OK","data":{":ApplicationTermsOfUse":"<p>Be nice to each other</p>\n"}}

5. Now reload the Account - Sign Up page and you should see the new General Terms of Use displayed.
