PDM Support to pyproject.toml Schema

🎯 Objective

This PR introduces comprehensive support for PDM (Python Development Master) configurations in the pyproject.toml schema. It aims to validate all current PDM settings while maintaining flexibility for future additions.

🛠 Changes

• Added a new pdm object to the tool section of the schema
• Implemented support for all current PDM configurations
• Designed the schema to be flexible for future PDM features
• Enabled validation for custom top-level PDM configurations

💡 Motivation

PDM is gaining popularity as a Python package and dependency manager. Adding support for PDM in the pyproject.toml schema will greatly improve the user experience for PDM users working with the Even Better TOML extension.

📘 Example

The new schema supports configurations like:

[tool.pdm.scripts]
start = { cmd = "python app.py", env = { DEBUG = "1" } }
test = { composite = ["pytest", "flake8"] }

[tool.pdm.dev-dependencies]
test = ["pytest", "pytest-cov"]

[[tool.pdm.source]]
name = "private"
url = "https://private.pypi.org/simple"
verify_ssl = true

[tool.pdm.resolution]
allow-prereleases = true
respect-source-order = true

# Custom or future configurations
[tool.pdm.custom_section]
custom_key = "custom_value"

🙏 Resources

Based on the official PDM documentation.
