✨ feat: drop Python 3.8 support#3170

CPython 3.8 reached end of life on 2024-10-07, more than 18 months ago, which meets the project policy for dropping a version. virtualenv now requires Python 3.9 or later to run and to create environments. virtualenv bundled the embedded wheel seed package only for Python 3.8, so this removes it: the wheel files, the 3.8 bundle entry, and the wheel handling in the upgrade tooling. The --wheel and --no-wheel options stay as no-ops, but the deprecation warning is louder and now states that virtualenv will remove them in a release after 2026-12. This also drops the macOS pyvenv launcher patch, which only applied to CPython 3.8.0-3.8.2, and updates packaging metadata, the CI matrix, tox environments, tests, and docs.

wheelseed package only for Python 3.8, so dropping 3.8 lets me remove it outright: thewheelfiles, the3.8bundle entry (which also orphanedpip-25.0.1andsetuptools-75.3.4), and the wheel handling intasks/upgrade_wheels.py. Removing the only 3.8-specific creator code, the macOS__PYVENV_LAUNCHER__patch that applied to CPython 3.8.0 through 3.8.2, falls out of the same cleanup.#3168removed the orphanedwheel-0.47.0on its own; this supersedes it, so close that one once this merges. PR#2884restored--wheel/--no-wheelafter an earlier removal broke Fedora and other downstream callers, so I kept both flags as no-ops rather than repeat that breakage. They now warn louder: the message states that virtualenv will remove them in a release after 2026-12, giving downstream tooling a deadline to stop passing them.
