Base Syntax
- Use the `$RUNNING_NG_PACKAGE_DATA` environment variable to refer to base configurations shipped with running-ng, such as `$RUNNING_NG_PACKAGE_DATA/base/runbms.yml`, regardless how you installed runnin-ng.
Benchmark Suites
- `DaCapo` gains an extra key `companion` to facilitate eBPF tracing programs.

Base Configurations
- Removing AdoptOpenJDK from the base configuration files. AdoptOpenJDK is now replaced by Temurin.
