chore: refine the hg-style.xml specification (#2457)

- Change the maximum wrap text length for XML to 120 (via `hg-style.xml`)
- Add a blank line between method definitions, inner class definitions, and static code blocks (via `hg-style.xml`)
- Add `<p>` tags to Javadoc blank lines (via `hg-style.xml`)
- `.xml` file leaves a blank line at the end (via `.editorconfig`)
- Class declaration requires a blank line before and after each line (via `hg-style.xml`)
- Javadoc line comment not in line (via `hg-style.xml`)
- `.properties` file leaves empty lines (via `hg-style.xml`)
- `.yaml` file braces `{}`, brackets `[]` remove spaces (via `hg-style.xml`)
