fix: update URL syntax in cypress.config.ts

[farhin23]

What this PR changes/adds

• The consumer and provider URLs in cypress.config.ts file have been updated with right syntax.

• In spec.cy.js file, the test - cy.get('[href="/my-assets"]').as('assets-menu-item').click();
  has been replaced with, cy.get('[href="/my-assets"]').first().as('assets-menu-item').click();

Why it does that

• In spec.cy.js file the cypress tests aims to visit two URLs - consumerUrl and providerUrl. These two URLs are configured in cypress.config.ts file as consumerUrl: 'http//localhost:18080', and providerUrl: 'http//localhost:28080', which do not follow the generic URL syntax and ends up showing unexpected behavior. Therefore, these two URLs has been updated with right syntax.

• In the introduction page of the DataDashboard there are two links with the tag href="/my-assets". The test cy.get('[href="/my-assets"]').as('assets-menu-item').click(); can not get executed successfully as cypress finds multiple elements of such kind.
  In this PR, cy.get('[href="/my-assets"]') has been chained with the first() command so it gets the first element of such type within the set of elements.
