Change absolute paths to relative paths.

Hi @randrag

If you allow collaboration, allow collaborators to create branches (protect main branch?) so that PRs could be created. Alternatively I suggest updating your input file paths from an absolute path into a relative path. Its easier for outsiders to run your code😁

module Day01 =
  let getInput () =
    System.IO.File.ReadLines($"{__SOURCE_DIRECTORY__}/input01.txt")
    |> Seq.map int64
