Description

• Return early from espp::FileSystem::remove(path, error_code) if the path does not exist (error_code is set by std::filesystem::status).
• Add check to example for ensuring fale/error_code are properlyset when trying to remove a non-existent file.

Motivation and Context

• Adds a missing check for completeness to espp::FileSystem::remove(path, error_code).
• Ensures the code doesn't attempt to remove a file that doesn't exist, which could lead to unnecessary error handling.

How has this been tested?

• Build and run file_system/example on qtpy esp32s3

Screenshots (if appropriate, e.g. schematic, board, console logs, lab pictures):
