Warning: ignoring input sourcemap for ember-testing.js while build after update to ember-source v6.1

After upgrade to ember-source v6.1 i'm getting in the project following warning:

Warning: ignoring input sourcemap for ../rewritten-packages/@embroider/synthesized-vendor/vendor/ember/ember-testing.js because ENOENT: no such file or directory, open '/home/user/projects/test/new-app/node_modules/.embroider/rewritten-packages/@embroider/synthesized-vendor/vendor/ember/ember-template-compiler.js.map'

Reproduce

1. ember new new-app --embroider --pnpm --typescript
2. ember s

Part 1 of the issue is ember-source didn't include the source map2: emberjs/ember.js#20850

Part 2 of the issue is https://github.com/embroider-build/embroider/pull/2164/files#diff-f8d6d1f14d39a8b63e24a8f0dd11dbc5b9c931b006354e3139de3c8844ea337c needs to copy over the source maps, probably conditionally, as there are old versions of ember-source that doesn't have them out there. Or it could scrub the file content clean of the invalid source map reference before writing it back out.

As an aside, I think that code is bugged. It seems like @ef4 had a typo in there that wrote the content of the template compiler into the wrong file name. Apps that are consuming the template-compiler that way (with app.import() it seems?) are probably broken right now.

@ef4 @chancancode is this issue fixed by #2305 or?

I think Ed expects it would, as long as you are not doing app.import on the template compiler 👍
