[RongtongJin]

Make sure set the target branch to develop

What is the purpose of the change

Recently we released 4.9.4 LTS version. The LTS version is the long-term support version. Subsequent bug fixes will be backported to this version from the trunk in a timely manner. We have created a 4.9.x branch, which is used for the long-term repair of bugs in RocketMQ 4.9.x.

This pull request will now merge the code in 5.0.0-beta into the develop branch. All the new features of RocketMQ 5.x will be in the develop branch later. Let’s look forward to the first version of RocketMQ 5.0.

Verifying this change

Follow this checklist to help us incorporate your contribution quickly and easily. Notice, it would be helpful if you could finish the following 5 checklist(the last one is not necessary)before request the community to review your PR.

• Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
• Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Write necessary unit-test(over 80% coverage) to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• Run mvn -B clean apache-rat:check findbugs:findbugs checkstyle:checkstyle to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.
• If this contribution is large, please file an Apache Individual Contributor License Agreement.
