Describe the feature

Would be great if Zed could support .git-blame-ignore-revs file stored in the project, which contains hashes of commits to avoid when showing change history (for example skip them in git blame, both inline and in the editor gutter). This is often used to hide modifications which are not really helpful or otherwise useful to understand the actual meaningful changes, such as project-wide code reformatting after updating the formatting tool or its settings. 👍
