Remove println! in rewrite_static()

[Creative0708]

There's an extraneous println!() in rewrite_static in items.rs:

rustfmt/src/items.rs

Lines 1992 to 2000 in e494418

	fn rewrite_static(
	context: &RewriteContext<'_>,
	static_parts: &StaticParts<'_>,
	offset: Indent,
	) -> Option<String> {
	println!("rewriting static");
	let colon = colon_spaces(context.config);
	let mut prefix = format!(
	"{}{}{}{} {}{}{}",

This causes rustfmt to add "rewriting static" to the top of every file that triggers rewrite_static() when formatting:

This PR removes the println!(). Nothing fancy, I assume this was a mistake.

Oops, sorry. Didn't see #6210 for some reason.
