Reformat cached_network_image_web for the current Dart formatter

[rickdijk]

✨ What kind of change does this PR introduce? (Bug fix, feature, docs update...)

Bug fix (CI). Pure reformat of cached_network_image_web, plus a patch bump.

⤵️ What is the current behavior?

The workflows install whatever Flutter stable is current, and the formatter's style changed, so the Format job fails on main: https://github.com/Baseflow/flutter_cached_network_image/actions/runs/35819343307 (platform_web) and https://github.com/Baseflow/flutter_cached_network_image/actions/runs/33173987545 (web)

🆕 What is the new behavior (if this is a feature change)?

dart format . output from Dart 3.13.2 (Flutter 3.47.2 stable), with no hand edits, in its own PR as AGENTS.md asks. Version 2.0.0 → 2.0.1, with a CHANGELOG entry.

💥 Does this PR introduce a breaking change?

No

🐛 Recommendations for testing

Ran locally: dart format --set-exit-if-changed ., flutter analyze (no issues), flutter test --platform chrome (1 passed). On CI, check that Format now passes in both web and platform_web.

Companion to PR 1045, which fixes the cached_network_image workflow. web.yaml has no workflow_dispatch trigger, so this PR is also what gets it a fresh run.
