Troubleshooting & FAQ

[sunnydean]

• Rename page to FAQ and update sidebar menu.
• Group questions by theme (Portal, Platforms, Data, Workflows, Community).
• - FAQ - add some questions that weren’t asked - group them somehow in sections - present it in sections
• Reformat "Issues Regarding EarthCODE" as question-answer.
• Clarify where to get support for each component (Portal team vs. Platform support).
