bug: Built wheels no longer contain Python source files since release 0.2.5

[knobix]

Description of the bug

The Python wheel available at PyPI for release 0.2.5 does not contain any Python source files. The same applies for Python wheels that are built locally.

To Reproduce

Looking at the Python wheel for release 0.2.5 available at PyPI yields following output:

$ unzip -t mkdocstrings_python_legacy-0.2.5-py3-none-any.whl
Archive:  mkdocstrings_python_legacy-0.2.5-py3-none-any.whl
    testing: mkdocstrings_python_legacy-0.2.5.dist-info/METADATA         OK
    testing: mkdocstrings_python_legacy-0.2.5.dist-info/WHEEL    OK
    testing: mkdocstrings_python_legacy-0.2.5.dist-info/entry_points.txt         OK
    testing: mkdocstrings_python_legacy-0.2.5.dist-info/licenses/LICENSE         OK
    testing: mkdocstrings_python_legacy-0.2.5.dist-info/RECORD   OK
No errors detected in compressed data of mkdocstrings_python_legacy-0.2.5-py3-none-any.whl.

The same output is given for locally built Python wheels.

Expected behavior

The Python wheels should contain the required Python source files.

Environment information

$ python3.11 -m mkdocstrings_handlers.python.debug
- __System__: FreeBSD-13.4-RELEASE-amd64-64bit-ELF
- __Python__: cpython 3.11.11
- __Environment variables__:
- __Installed packages__:
  - `mkdocstrings-python-legacy` v0.2.5

Additional context

Adding back following lines to section [tool.pdm.build] in pyproject.toml that were removed by commit e6f429e should remedy the issue:

package-dir = "src"
editable-backend = "editables"
includes = ["src/mkdocstrings_handlers"]

Thanks for the reports @knobix! Fixed in v0.2.6 🙂
