Fix number property generation in featureset feature template (#11851)

https://mapbox.atlassian.net/browse/MAPSAND-2672

## Summary

- Fix `featureset_feature.kt.ejs` template: for `number`-typed
featureset properties, emit `getNumberProperty(...)?.toDouble()` /
`?.toLong()` instead of the non-existent `getDoubleProperty()` /
`getLongProperty()` (which don't exist on `com.mapbox.geojson.Feature`)
- Generated files updated by running `generate-all` and `update-api`
