[BUG] Support for directories containing whitespaces

[abeldantas]

Current Behavior:

When we perform code-review-gpt review on a repo with staged changes in directories with whitespaces, we get:
ERROR Error: Failed to get files with changes: {}

Steps To Reproduce:

Stage changes and review a file under:
Scripts/Some Folder/test.sh

Environment:

• Os: MacOs
• Node: v20.6.0
• npm: 9.8.1

Hey, thanks for your issue. Feel free to create a PR to fix this. It is a problem with the filtering of the files by extension.
