Code review: isSubdir #11454
Description
We currently vendor isSubdir from Deno's stdlib, and their documentation (or code, take your pick) describes parameters src and dest precisely backward. We use this call in Quarto ourselves: https://github.com/quarto-dev/quarto-cli/blob/main/src/deno_ral/fs.ts#L49. We need to review all callers of this function for accuracy, and then fix the function code or docs.
