style(docs-infra): fix docs examples for tslint rules related to whitespace (#38143)

This commit updates the docs examples to be compatible with the `align`,
`space-before-function-paren` and `typedef-whitespace` tslint rules.

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.
