Support negative weights in front matter

Porting a site over from Hugo. Got this error.

Error: Reason: YAML deserialize error: Error("weight: invalid type: integer `-1`, expected usize", line: 3, column: 9)

I can’t undo the engative weights since this will disrupt the order of the pages. Is it possible to support negative weights?

Not planned not. You can just space out weights to keep the order of the pages
