Types broken in v3.39

I'm attempting to update from v3.38.4 to v3.39.0 and am getting lots of type errors: ``` Error: src/index.js(3,21): error TS2307: Cannot find module 'fastly:env' or its corresponding type declarations. Error: src/index.js(4,37): error TS2307: Cannot find module 'fastly:html-rewriter' or its corresponding type declarations. Error: src/index.js(27,1): error TS2304: Cannot find name 'addEventListener'. Error: src/index.js(30,12): error TS2304: Cannot find name 'FetchEvent'. Error: src/index.js(31,22): error TS2304: Cannot find name 'Response'. Error: src/index.js(37,22): error TS2304: Cannot find name 'URL'. ``` I have the following at the top of my index.js: `/// <reference types="@fastly/js-compute" />`. When I go to its definition however it shows dist/index.d.ts with the following contents: ```js export {}; ``` The types are gone! Appears to be caused by #1269
