Update main.py

The suggested change improves the validate_yaml_file function in a few key ways:
Use of context manager:
The new version uses a with statement to open the file, which ensures that the file is properly closed after reading, even if an exception occurs. This is a best practice for file handling in Python.
Combined exception handling:
The original version had separate except blocks for yaml.YAMLError and FileNotFoundError. The new version combines these into a single except clause, which simplifies the error handling.
More specific error message:
The new version includes the specific exception message in the ConfigError that's raised, which can provide more detailed information about what went wrong.
4. Consistent return:
The function now always either returns the loaded YAML data or raises a ConfigError. This makes the function's behavior more predictable.
These changes make the function more concise, easier to read, and slightly more efficient in terms of resource management (due to the use of the context manager). It also provides more informative error messages, which can be helpful for debugging.
