fix(services/s3): omit default ports

[yufan022]

try fix #4249

The default port is omitted by Url::from(xx) when sending request:

opendal/core/src/raw/http_util/client.rs

Lines 89 to 95 in 4c1752b

	let mut req_builder = self
	.client
	.request(
	parts.method,
	reqwest::Url::from_str(&uri.to_string()).expect("input request url must be valid"),
	)
	.headers(parts.headers);

They are not ignored when calculating signatures:

opendal/core/src/services/s3/core.rs

Lines 382 to 384 in 4c1752b

	let url = format!("{}/{}", self.endpoint, percent_encode_path(&p));
	let mut req = Request::put(&url);
