Fix source maps in published packages

I noticed this problem from this warning in my build:

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

Indeed, it seems like as of 5.10.0-beta.1, we stopped publishing
source maps:

https://unpkg.com/browse/[email protected]/dist/

...despite having every intention to do so still.

Last good version:

https://unpkg.com/browse/[email protected]/dist/

It took me way to long to spot this, but the problem is in the
extension; in the broccoli build, they had a `$name.map` filename,
whereas in the new build (#20675) it's `$name.js.map`.

Adjusted the entries in package.json to match; also removed the
types publish script that was accidentally included in the tarball.

As for my original quest to fix the warning, it turns out this is
not sufficient. The file is placed there by @embroider/compat these
days:

embroider-build/embroider#2164

It'll have to be updated to also emit the source map file (if it is
present, since this has been broken for a while).

But this is a prerequisite to fixing that.
