deno fmt should respect prettierrc and prettierignore did't land

[axetroy]

Release Note:

fix: deno fmt should respect prettierrc and prettierignore (#3346)

Because flags.rs still using v0.23.0

deno/cli/flags.rs

Lines 14 to 18 in 2cd22b5

	macro_rules! std_url {
	($x:expr) => {
	concat!("https://deno.land/std@v0.23.0/", $x)
	};
	}

and see the source code: https://deno.land/std@v0.23.0/prettier/main.ts

Here's a question:

how to synchronize deno and deno_std versions

Move discussion to #3320
