wheel tags command displays invalid filenames on stdout

[MKuranowski]

To quote python -m wheel tags --help:

The output filename(s) will be displayed on stdout for further processing.

This should make usage in shell scripts like FIXED_WHEEL_PATH=$(python -m wheel tags ...) (with single input file) possible.

However, instead, the stdout is spammed with "added: 'module/some/file.py'" lines, which are not valid filenames. Such logging should be sent to stderr instead.

Example output of `python -m wheel tags`

$ python -m wheel tags --python-tag py3 --abi-tag none --platform-tag manylinux2014_x86_64.manylinux_2_17_x86_64 dist/impuls-0.6.0-cp312-cp312-linux_x86_64.whl 2>/dev/null
