fix(ci): fix flaky e2e tests - ignore temporary files when checking for out of bound symlinks

[CefBoud]

Addresses part of #11667

Description

This PR fixes errors that happen frequently in the CI 1, 2.

These issues arise when walking through a directory, where temporary files—like Git lock files—are scanned but may be deleted by the time their handlers execute.

Thank you @CefBoud . This flakiness appeared recently. Had you chance to check what change may introduced this issue? Just wonder why it started to happens

@pasha-codefresh
I did not observe any significant changes in this failing code path. However, I did notice that the version of Git being used by the job has been updated recently to 2.47.0, which was released in early October. This is simply an observation and does not necessarily imply that the issue originates from Git.
The error failed to walk for symlinks in the path.Walk function is not new; it has been encountered before, as noted in #11667.

This seems safe and reasonable. If a file doesn't exist, it can't provide a path for traversal.
