Add another layer of containering to avoid messing up the <details>
container. Which somehow didn't affect the English page, but it broke
on all other languages.
- Add links to the original page and to the main troubleshooting page
at the end of each page
- Re-title some headers
- Consolidate boot/software/other issues into 'post-install issues'
- Add warning on ssloth and skater to prevent confusion of the two
- Reword landing page slightly
Under this new structure, troubleshooting pages are now split into
respective guide pages. With SafeB9SInstaller issues as an include
step, this allows to have a complete troubleshooting section for each
guide page, shrinking the previously-massive troubleshooting page into
understandable fragments.
