Revert d3-geo to 2.x to fix Node CJS consumers

[mfedderly]

While building testing for the various consumer scenarios, it caught that the d3-geo upgrade from the @turf/buffer migration to TypeScript actually caused failures in node@18 from CJS. I believe this is because d3-geo incorrectly points to an ESM file when it is expecting a CJS one. See arethetypeswrong with node16+cjs.

The original upgrade was from d3-geo@1 to d3-geo@3, but d3-geo@2 hadn't yet been moved to ESM and so we can take that instead.

The failure that was caught by the consumer testing:
