fix(runtime-core): type ExposedKeys removed defined properties on com…

[akotulu]

Fixes typo made in pull request #3399.

IDEs using Vue language service with TypeScript support will have all the local component variables displayed as red with an error Vue: X does not exist on type. ExposedKeys will compare empty string ('') to extend Exposed type which will always fail cause builtin string can't extend custom class.

Tested with:
PHPStrom 2024.3.1.1
TypeScript 5.7.3
Vue LS 2.2.0

This change will break the existing test case in packages-private/dts-test/defineComponent.test-d.tsx. You can verify this by running pnpm run test-dts.

By the way, could you provide a test case or a minimal reproduction to clarify the issue this PR is addressing? Thanks!

I can confirm this issue using Webstorm LTS 2024.2.5 Build #WS-242.24807.6
I created a reproduction repo: https://github.com/DC240/12697-runtime-core-error-reproduction

It is however, only the case if I'm using class based components using vue-facing-decorator. Using the composition API, the component resolves correctly. We have a lot of older projects at our company for which there is no budget to convert them to composition API, so for us it is a pretty common and annoying problem.

It took whole weekend to figure out where this issue with Intellij ideas came from. I will look at the tests when I have time again. Probably end of the week.
