[KYUUBI #4005] Remove deprecated from description of kyuubi.frontend.…

…bind.host

### _Why are the changes needed?_

Unlike `kyuubi.frontend.bind.port`, which is deprecated and replaced by `kyuubi.frontend.thrift.binary.bind.port`, `kyuubi.frontend.bind.host` is still encouraged to use, and it can be overwritten by `kyuubi.frontend.<protocol>.bind.host`, e.g. `kyuubi.frontend.thrift.binary.bind.host`, `kyuubi.frontend.thrift.http.bind.host`, `kyuubi.frontend.rest.bind.host`, `kyuubi.frontend.mysql.bind.host`

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [x] [Run test](https://kyuubi.apache.org/docs/latest/develop_tools/testing.html#running-tests) locally before make a pull request

Closes #4005 from pan3793/doc.
