This PR fixes two problems in the cascading deletion page:
- The indentation of list items should be 2 spaces for unordered lists,
or 3 spaces for ordered lists. We should avoid using 4 spaces as
indentation because 4-spaces indentation has special meaning in
markdown.
- The garbage-collection page was moved to a new place. With redirect
records for English site, there seems no obvious problems. However,
for localization teams, such redirection records don't exist. It is
super easy to create a dangling link in localized pages.
