### Summary
During the import process of a project from GitHub to GitLab, there is an issue with the usage of GitHub-generated email IDs and the addition of an "unverified" label on the PR merge commits. This behavior results in incorrect email IDs being associated with the commits and the unverified label misleadingly applied to the imported data.
<!-- Summarize the bug encountered concisely. -->
### Steps to reproduce
- In GitHub use Github AutoMerge feature https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/automatically-merging-a-pull-request
- Perform a project import from GitHub to GitLab.
- Observe the imported PR merge commits.
- Check the email IDs associated with the users who made the PR merge commits.
- Notice that the GitHub-generated email IDs are used instead of the users' public email IDs.
- Verify the presence of the "unverified" label on the PR merge commit entries.
<!-- Describe how one can reproduce the issue - this is very important. Please use an ordered list. -->
### Example Project
<!-- If possible, please create an example project here on GitLab.com that exhibits the problematic
behavior, and link to it here in the bug report. If you are using an older version of GitLab, this
will also determine whether the bug is fixed in a more recent version. -->
### What is the current *bug* behavior?
The import process uses GitHub-generated email IDs instead of the public email IDs of the users for PR merge commits. Additionally, an "unverified" label is wrongly added to the PR merge commit entries, even though there may not be any verification issue with the email IDs.
### What is the expected *correct* behavior?
During the import of a project from GitHub, the PR merge commits should correctly use the public email IDs of the users involved. The imported data should not have an "unverified" label attached to the PR merge commit entries.
<!-- Describe what you should see instead. -->
### Relevant logs and/or screenshots


<!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code
as it's tough to read otherwise. -->
