Closes #1111

Hi @kne42, we'd love your review on this to make sure all the updates were made correctly. Also, regarding the FAQ, we are moving forward with directing users to the Portal documentation site instead of FAQ page on the Portal. Ultimately, the Portal FAQ page will be disabled. I will coordinate with Jun about this.

I'm not sure how to address the failing test, I'm afraid.

@kne42 can you help with this as well?

@melissawm I asked @kne42 about the failing test and she shared that since you are trying to merge the PR from a fork, you need to set up the E2E_CONFIG environment variable to this value
{"url": "http://localhost:8080","authorName":"Irene de Teresa Trueba","authorOrcId":"0000-0002-4691-9501","runId": "138"}

Closing in favor of opening a PR against this repo and not a fork.
