chore(deps): combine the open Renovate updates

[jaysonsantos]

Summary

This pull request combines the open Renovate updates into one change. It replaces #309, #294, and #288.

• Update Sphinx from 1.8.1 to 9.1.0. Remove the duplicate Sphinx line in docs/docs_requirements.txt.
• Update Pygments from 2.7.4 to 2.20.0. This version fixes a security issue (chore(deps): update dependency pygments to v2.20.0 [security] #288).
• Update the ruff-pre-commit hook to v0.16.8 and the commitizen hook to v4.19.0.
• Use Python 3.14 in the lint job and in the publish workflow.
• Change intersphinx_mapping in docs/conf.py to the named-tuple format. Sphinx 8 and later do not accept the old format.

Tests

• sphinx-build -W --keep-going -b html docs <out> with Sphinx 9.1.0 on Python 3.14: the build succeeds with no warnings.
• prek run --all-files: ruff check, ruff format, and commitizen pass. The trailing-whitespace and end-of-file-fixer hooks find old problems in docs/_static, docs/_sources, and docs/index.rst. This pull request does not change these files.

Then updates hooks, one by one.
