Suggestion is to edit the 2nd example in the docs for command spo folder roleinheritance reset.
For the folderUrl option we can both provide "Shared Documents/TestFolder" and "/sites/project-x/Shared Documents/TestFolder". It would be nice if we have these 2 examples in the docs.

Therefore I suggest to edit the 2nd example in the docs to:

m365 spo folder roleinheritance reset --webUrl "https://contoso.sharepoint.com/sites/project-x" --folderUrl "/sites/project-x/Shared Documents/TestFolder" --confirm
