NEP-29 - require minimum Python version 3.11 (#7499)

pavoljuhas · web-flow · commit 325436213a47 · 2025-07-16T19:38:01.000Z
NEP-29 require minimum Python version 3.11 Roll forward of #7338 because internal documentation build can now run with Python 3.11. A few capitalization fixups are here too. Revert "Permit installation for Python 3.10 (docs build only) (#7445)" This reverts commit 609d93d. Fixes #6648
