This is a modified version of commit c6d59e66f3630108d84dcce59aaae871e4eb2b30 by Daria Bialobrzeska:
Start showing inlined functions in stack trace (#208)
* Start showing inlined functions in stack trace * Fix notifier tests * Added change to CHANGELOG
I selected only the code changes in the errors packages and also applied it on the version 1 of this package (which is still used by notary as of writing).
This fixes the backtrace generated when using go 1.24, thus fixing the TestUnwrapPkgError failure.
