fix(patch): Use String(reflecting: error) for printing errors

[MahdiBM]

Description

A few (mostly server side) packages like PostgresNIO have a generic description in their errors, while providing the full error info in debugDescription.
Using String(reflecting: error) we can make sure the debugDescription is preferred when transforming the error into an String.

Sample error:

Benchmark MyBenchmark failed with PostgresDecodingError – Generic description to prevent accidental leakage of sensitive data. For debugging details, use String(reflecting: error).

How Has This Been Tested?

Please describe the tests that you ran to verify your changes.

Minimal checklist:

• I have performed a self-review of my own code
• I have added DocC code-level documentation for any public interfaces exported by the package
• I have added unit and/or integration tests that prove my fix is effective or that my feature works

Good idea to provide more detailed error messages.
