Bug report

Bug description:

I just saw the following deprecation warning in the GitHub Actions log for a project I contribute to:

/opt/hostedtoolcache/Python/3.12.2/x64/lib/python3.12/tarfile.py:2221: DeprecationWarning: Python 3.14 will, by default, filter extracted tar archives and reject files or modify their metadata. Use the filter argument to control this behavior.    warnings.warn(

Unfortunately, the warning doesn't tell me anything about which line in the project is triggering the warning. The warning points to the line intarfile.py inside the function that has the deprecation warning, rather than the line in my project that's calling thetarfile function in the depreacted way. We should set a stacklevel here to rectify this (I think stacklevel should be set to3?):
