This commit changes "deno outdated" subcommand to
error out if run in a directory that has no config file
(including parent directories). This matches
"pnpm" behavior.
Also added tests for filtering that yields no results,
to ensure that it exists cleanly, that also matches "pnpm"
behavior.
Closes https://github.com/denoland/deno/issues/27287
