fix(cli): prevent generate task from crashing (#5693)

this pr is motivated by a scneario where running `npx stencil generate`
would result in either an error or an early return:
```
npm run generate

> gen-test-1@0.0.1 generate
> stencil generate

[49:23.1]  @stencil/core
[49:23.2]  v4.17.0 ♨️
```

note: the reported error was never reproduced locally, only the early
return.

technically, this was introduced in v4.17.0, when we switched over to
using esbuild for production builds. however, this has been present in
any build that is esbuild-based since we migrated the cli submodule to
esbuild (where we had a mixed rollup-esbuild build during the migration
for dev builds).

removing this alias eliminates dynamic imports in the CJS output of the
cli submodule:
```
const {
    prompt: r
  } = await import('../sys/node/prompts.js')
```
which wouldn't run properly, causing the error/early return.

this change does cause an increase in bundle size, as we end up
importing more of prompts.js than we do. to mitigate this, we direct
the cli module to the export we actually use (leading to less getting
bundled in the cli module).

fixes: #5692

STENCIL-1294 cannot identified the prompts.js as a function? ?
