fix(emit): don't emit test files

This fixes a bug introduced in #4315, which upgraded to TypeScript 5. In
that PR we had to change the way that we prevented certain files from
being emitted by the typescript compiler because in the 5.0 release our
previous approach stopped working.

However, in porting over to a new approach that worked with TS 5.0 there
was an oversight. I misunderstood the intent of the old code as being to
merely prevent writing `.d.ts` files in the output, when actually it was
about preventing the compiled JavaScript from being written for
`.e2e.ts` and `.spec.ts` files.

This change ensures that we no longer emit these files.
