chore(ci): modify test snapshots to fix CI failures

[Copilot]

CI failing on snapshot mismatches in pool tests. Rendering output from maplibre-native changed slightly since snapshots were last updated.

Changes

Updated 5 snapshot PNG files:

• pool__large_coordinates_handled.snap.png
• pool__sequential_errors_dont_break_pool.snap.png
• pool__style_switching_.snap.png
• pool__style_switching_-2.snap.png
• pool__style_switching_-3.snap.png

All affected tests (large_coordinates_handled, sequential_errors_dont_break_pool, style_switching_) now pass with just ci-test vulkan.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

we shouldn't use pngs as snapshots - too flaky. Perhaps one day there could be a better way to do this?
