YaML path '$' fails with `failed to find path ( $ )`

[wjam]

Describe the bug Attempting to build a YaML path that points to the root of the YaML document (so just $) fails. The errors in the stack of errors are failed to read node, failed to filter from ast.File, failed to find path ( $ ), and node not found.

To Reproduce

Example failure - https://go.dev/play/p/UHfjmW_lYLf

Expected behavior A path is created that points to the root of the YaML document. Alternatively, the YaML path should be treated as invalid when attempting to create it.

There's an easy enough fix for that: https://github.com/nieomylnieja/go-yaml/commit/0e9c52f588e6f2df9b9b93255e664304ebc93925.

I'm not sure if this project is actively maintained anymore though, I'm using a fork myself.
