sha256 checksum of install-pdm.py does not match

[bmcandr]

The sha256 checksum for install-pdm.py currently shown on the website does not match the file. The website says the checksum of the current install-pdm.py file should be ce0a116987b2667231391d13dd005006433114033cac74aa18f0b2dec5538d03.

Generating the checksum locally or checking with an online tool returns a different sha256 checksum:

$ curl -sSL https://raw.githubusercontent.com/pdm-project/pdm/main/install-pdm.py | shasum -a 256
06abd94a6678636eba640529bf91b242759363c45d3620cdfabaa0053d826b30  -
