test: [M3-7317] - Combine update and delete VPC tests

[carrillo-erik]

Description 📝

This PR saves 1 test by combining the former update and delete VPC test on the VPC landing page.

Changes 🔄

• Now, the combined test mocks two separate VPC instances. It updates one VPC, confirms the updates are reflected in the landing page, then deletes this VPC and confirms that the deletion is reflected in the landing page as well. Then, it deletes the second VPC instance and confirms that the deletion is reflected in the landing page by reverting back to the empty state of the VPC landing page.
