Support for PEP 440 versions

[edvilme]

This pull request refactors how Python version strings are handled and compared throughout the codebase, replacing custom logic with the PEP 440-compliant @renovatebot/pep440 library. This ensures more accurate version validation, comparison, and display, and improves reliability across Python environment management features. Additionally, it updates dependencies and cleans up related code.

Python version handling improvements:

• Replaced all custom version parsing, comparison, and validation logic (e.g., shortVersion, isGreater, compareVersions) with PEP 440-compliant functions (pep440Valid, pep440Compare, etc.) from the @renovatebot/pep440 library in src/managers/common/utils.ts and throughout the codebase. This affects environment sorting, latest version selection, and version string shortening. [1] [2] [3] [4] [5]
• Updated all usages of the old shortVersion function to use the new shortenVersionString, which leverages PEP 440 parsing for more accurate and consistent version display. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]
• Updated version sorting and selection logic in conda and environment managers to use PEP 440 comparison for more reliable and standards-compliant ordering. [1] [2] [3] [4]

Validation and compatibility checks:

• Replaced regex-based PEP 440 validation in pyproject.toml validation with pep440Valid for more robust version checking. [1] [2]
• Updated extension compatibility checks to use PEP 440-compliant version comparison, ensuring accurate enforcement of minimum required extension versions. [1] [2]

Dependency and configuration updates:

• Added @renovatebot/pep440 as a dependency in package.json and reformatted some configuration for clarity. [1] [2]

These changes collectively improve the accuracy, maintainability, and standards compliance of Python version handling across the extension.
