Fix build, invalid whitespace

[mkaz]

Description

I introduced a whitespace conflict with build artifact from my change #15612

This fixes the issue, I'll check with @nosolosw for updating test, it looked green on my PR.

Types of changes

Documentation, whitespace

[mkaz]

A second run and the whitespace was reversed, after running npm run docs:build
I think the build error is unrelated to my change.

I've also seen this on another PR, these commits:

• 44bc955 (whitespace changed)
• bde0e03 (whitespace reverted)

At the time I thought it was committed by error (keyboard mashing), but I think it might've originated from the git hook.

I see that the changes always happen in packages/core-data/README.md 🤔 I'm taking a look into that.

#15626 is probably related.

@mkaz @talldan #15679 fixes the issue. It was more involved than I expected.
