[bazel.build] Problem with /start/cpp

### Page link:

https://bazel.build/start/cpp

### Problem description (include actual vs expected text, if applicable):

In Stage 2 ,there is sentence saying "you can see that hello-world depends on **the same inputs** as it did before".

That is wrong! Stage 2's hello-world clearly depends on **different** input compared to Stage 1.

### Where do you see this issue? (include link to specific section of the page, if applicable)

https://github.com/bazelbuild/bazel/blob/076ce3e64df73d5363cba6efb3b7f68bcebe6a5e/site/en/start/cpp.md?plain=1#L282

### Any other information you'd like to share?

_No response_

Open site/en/start/cpp.md around line 282 and compare the Stage 1 and Stage 2 examples. Check whether the sentence about hello-world having the same inputs is accurate, then revise the documentation so it matches the examples. The page link in the issue provides the relevant section.
