chore(ci): modify test snapshots to fix CI failures (#130)

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`.
