[Bug] Make release note generation more resilient by gracefully handling invalid changelog fragments

[ananzh]

Description

Currently, the release note generation script (scripts/generate_release_note) fails entirely if any single changelog fragment has invalid formatting or YAML syntax errors. This causes the entire process to abort, preventing the generation of release notes even when most fragments are valid.

For example, if a fragment has incorrect YAML indentation:

feat:
- "[navigation] Adjust the appearances..." # incorrect indentation

This PR modifies the release note generation script to:

• continue processing when encountering invalid fragments instead of aborting
• add error handling around file reading, fragment validation, and YAML parsing
• report failed fragments with detailed error messages

The changes make the script more resilient while maintaining strict validation rules. Invalid fragments are skipped and reported, allowing the process to continue with valid entries.
