Remove symbols statefulset

Starting in Sourcegraph 6.4, the Symbols and Searcher services are now combined, for easier operation, simplified architecture, and better resource utilization.

Customers can delete the service if not deleted automatically, and may want to consider reallocating resources previously given to symbols to searcher. Environment variables should be copied over from symbols to searcher.

Test plan: This deployment ran for ~2 weeks on S2 and dotcom already and has signoff from team-product-platform.
