fix : UpstreamCheckUtils.checkUrl param add protocol.

[BraveheartStone]

If the protocol parameter is not added, when shenyu.upstreamCheck.enabled=true is configured in shenyu-bootstrap, the port numbers checked in the UpstreamCheckUtils.checkUrl method will all be port 80. The host using the HTTPS protocol will not be checked on port 443, resulting in the health check failing continuously.

Make sure that:

• You have read the contribution guidelines.
• You submit test cases (unit or integration tests) that back your changes.
• Your local test passed ./mvnw clean install -Dmaven.javadoc.skip=true.
