Summary

since the introduction of serde_saphyr (https://github.com/j178/prek/pull/1087/files) our check-yaml hook fails with errors like this:

redacted.yaml: Failed to yaml decode (!!binary scalar is not valid UTF-8 at line 26, column 9)

which refers to this kind of content in a .yaml file:

response:
      body:
        string: !!binary |
          g5tmEZW9HiKiqA8BGikL5++PkGHuP3+p/1+/WHOrSONjGb........

This didn't cause any issues for us before the change
