🐛 Update launch json

[sebastianrath]

The VScode runner configurations are now relabeled.

• Launch CLI (main.ts)
  If selected, main.ts will be executed. This is the main entry point for the command-line application. Please modify the launch.json (see code-snippet below) to simulate a CLI call. In addition to "args", add "cwd" to set a current working directory. Please note, the startup time for this might take significantly longer than in a final production build.

Example invoke: snow status

• Launch Test (test/*)
  Execute a unit-test file. Please open and select a test-file from the test directory in the VScode editor, and trigger the execution. Eventually all tests in this file will be executed. To execute all tests of the entire test directory, execute npm run ava from the command-line.

• Launch Benchmark
  Use to debug benchmarks/snowfs-vs-git.ts. If you are interested in running the actual benchmark, consider to execute npm run benchmarks from the command-line.
