When repacking a wheel, the following error is raised

Context

• This occurred for new builds starting on 2025/01/09 in the edge-product repository
• We are building a wheel and then repacking to an egg using the following pyproject.toml:

[build-system]
requires = ["setuptools>=64"]
build-backend = "setuptools.build_meta"

[project]
name = "enthought_edge"
license = {text = "Proprietary"}
authors = [
    { name = "Enthought, inc.", email ="[email protected]"} 
]

dynamic = ["version", "dependencies"]

[project.urls]
Homepage = "https://www.enthought.com"
Documentation = "https://docs.enthought.com/edge"
Support = "https://edge-support.enthought.com"

[tool.setuptools]
include-package-data = true

[tool.setuptools.dynamic]
dependencies = {file = ["requirements.txt"]}
version = {attr = "edge.__version__"}

[tool.setuptools.packages.find]
include = ["edge", "edge.*"]

• Investigating generation of the PKG-INFO version, it appears that the latest setup tools version 75.8.0 released on 2025/01/08 allows "dynamic" pkg-info metadata version computation, likely causing the version info to be computed to 2.2. Settting "setuptools==75.7.0" resolves the issue.

Yes, the current version of okonomiyaki supports PKG-INFO metadata version upto 2.1. We should add support for PKG-INFO Metadata 2.2

Updating line 2 with requires = ["setuptools>=64, <75.8"] solves the problem
