* Provide a better error message from the stderr of a CLI invocation that failed with a fatal

* - If the CLI invocation failed with a fatal error, this returns that fatal error, followed by

* ### Example
*
* ```
* Running TRAP import for CodeQL database at /home/runner/work/_temp/codeql_databases/javascript...
* A fatal error occurred: Evaluator heap must be at least 384.00 MiB
* A fatal error occurred: Dataset import for
* /home/runner/work/_temp/codeql_databases/javascript/db-javascript failed with code 2
* ```
*
* becomes
*
* ```
* Encountered a fatal error while running "codeql-for-testing database finalize --finalize-dataset
* --threads=2 --ram=2048 db". Exit code was 32 and error was: A fatal error occurred: Dataset
* import for /home/runner/work/_temp/codeql_databases/javascript/db-javascript failed with code 2.
* Context: A fatal error occurred: Evaluator heap must be at least 384.00 MiB.
