Bug report

Bug description:

The dst variable in https://github.com/python/cpython/blob/main/Lib/venv/__init__.py#L396 should be named dest. Otherwise it throws the UnboundLocalError: cannot access local variable 'dst' where it is not associated with a value.

I have a PR that fixes this and also adds a test covering this code path.
This is occurring on Python 3.13 and 3.14.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Windows
