Ensure files_to_ignore is passed as a single arg

[johnlk]

As the title implies, this ensures that the argument is passed as a single string value that is whitespace delimited.

Improvements:

• Consider moving all the details related to how you're getting the "commit_diff" to a separate function. This will enhance the readability of the main() function, and adhere to the single responsibility principle.
• Variable "files_to_ignore" can have a clearer name to indicate it's an array.

get_commit_diff_for_pr() {
  local -r pr_number=$1
  local -A files_to_ignore=$2
  echo $(github::get_commit_diff "$pr_number" "${files_to_ignore[*]}")
}

main() {
  ...
  local -r commit_diff=$(get_commit_diff_for_pr "$pr_number" "${files_to_ignore[*]}")
  ...
}
