This changeset updates Sculpin from 3.2.0 to 3.3.2, which brings Twig 3 and Symfony 6.4:

Package	Change	Comparison
sculpin/sculpin	3.2.0 -> 3.3.2	diff
twig/twig	v2.16.1 -> v3.30.0	diff
symfony/*	v4.4 -> v6.4	diff
netcarver/textile	v3.7.7 -> v4.1.6	diff

The other lock changes are smaller psr/*, dflydev/* and polyfill packages that follow along. Twig 3 no longer supports conditions on for loops, so the four loops in the blog and talks templates now use if blocks instead.

This also clears all 21 composer audit advisories for our locked dependencies. Dependabot's security updates kept failing on these, because Sculpin 3.2 pins Twig 2 and Symfony 4.4.

Nothing should change on the website. The generated pages are identical before and after this change, apart from the internal .ignoreme.html dummy that now consistently holds the most recent talk. The Playwright tests from #153 pass as well.

Builds on top of #132 and #123

🔵 Needs a closer look

The Twig and Symfony major-version upgrades warrant human confirmation of the reported output comparison and passing end-to-end tests.

No open issues 🎉
