Rename build tag to envoy instead of proxywasm (#35)

 is incomplete, and in addition, it's ABI, proxy-wasm has design issues that prevent working with
 defaults appropriate for normal TinyGo applications. As this project is commonly used with Envoy,
 we provide a build tag, to work around these issues. If building an Envoy plugin, add
-`-tags=nottinygc_proxywasm` (or combine it with additional tags) to your TinyGo build flags. This
+`-tags=nottinygc_envoy` (or combine it with additional tags) to your TinyGo build flags. This
 will disable export of `malloc`/`free`/ and define a no-op `sched_yield` function.
