bug(pnpm): Add test to check/prove that pnpm builds are failing

[kamil-bielecki-bosch]

Add sythetic test to check how pnpm package manager behaves for some type of nested projects.

• Since last refactoring/rework of analyzer's PNPM package manager some of projects cannot be scanned anymore.
• There is the exception thrown during JSON parsing (output of pnpm run)
• This PR helps to reproduce the problem.
• We found, that commit 0eb1eea introduced new parameters for pnpm command (--json instead of --parseable and value for --recursive parameter), that leads to generate unparseable output.

Exception message generated:

PNPM failed to resolve dependencies for path 'frontend/package.json': JsonDecodingException: Unexpected JSON token at offset 1201: Expected EOF after parsing, but had [ instead at path: $
JSON input: .....-scope"
      }
    }
  }
]

@kamil-bielecki-bosch Please provide additional context, for example, could you figure out which commit broke this? Also, how does the test you added fail, does it throw an exception and which one?
