style(docs-infra): fix docs examples for tslint rule import-spacing (#38143)

This commit updates the docs examples to be compatible with the
`import-spacing` tslint rule.

This is in preparation of updating the docs examples `tslint.json` to
match the one generated for new Angular CLI apps in a future commit.
