071898da: Remove deprecated usage of Files component

Why: Since 8.3.0, you should use the Folder component instead for folders. For simplicity, the title prop has been renamed to name.

Migrate: Replace folders with the Folder component. Rename title prop to name.
```
- <Files>
- <File title="folder">
- <File title="file.txt" />
- </File>
- </Files>

+ <Files>
+ <Folder name="folder">
+ <File name="file.txt" />
+ </Folder>
+ </Files>
```
