Modify check function to provide a list of files with issues

[skytin1004]

Currently, when using the check functionality, only the file being retried is displayed as below

(.venv) C:\Users\sms79\dev\Phi-3CookBook>translate -l "zh" -chk
Checking translated files for errors in zh...
Checking files for zh: 100%|█████████████████████████████████████████████████| 95/95 [00:00<00:00, 113.15file/s]
Retrying E2E_Phi-3-FineTuning_PromptFlow_Integration.md for zh:  59%|████▋   | 24/41 [51:37<45:01, 158.90s/file]

The goal is to modify the check functionality to display a list of all files with issues, rather than just the single file being retried.

Example

(.venv) C:\Users\sms79\dev\Phi-3CookBook>translate -l "zh" -chk
Checking translated files for errors in zh...
Checking files for zh: 100%|█████████████████████████████████████████████████| 95/95 [00:00<00:00, 113.15file/s]

Summary of files with issues:
1. E2E_Phi-3-FineTuning_PromptFlow_Integration.md
2. Guide_Phi-3_Model_Deployment.md
3. Overview_Phi-3_Training_Workflow.md
