Change run_wasm_cli_with_css to run_wasm_with_css readme.md

[reeceyang]

It looks like the example is out of date, as the function to run is now called run_wasm_with_css

Thanks for the PR!

It looks like run_wasm_with_css is deprecated in favor of run_wasm_cli_with_css but I never got around to releasing cargo-run-wasm since then:

cargo-run-wasm/src/lib.rs

Lines 411 to 414 in 99181f0

	#[deprecated(note = "renamed to run_wasm_cli_with_css")]
	pub fn run_wasm_with_css(css: &str) {
	run_wasm_cli_with_css(css)
	}

I'll close this PR and release 0.4.0 to fix the issue.
Thanks for bringing this to my attention.
