Currently Snapcraft only do a `pip install .` operation when the setup.py file is found in the part's source tree[1], which is no longer the case with projects adhering to PEP 518[2] as such projects may have a pyproject.toml file in their source tree instead(e.g. OCRmyPDF[3]). This patch instructs Snapcraft to run the `pip install .` command when pyproject.toml is found in the source tree, according to the pip pull request that implements the support[4] and the Ubuntu package search results[5] this should be supported since core20.
