Improve Type Union Typings in the Docs

[dsanders11]

The phrasings that electron/docs-parser recognizes for string union types is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.

Fix these and add smoke tests with // @ts-expect-error to ensure type unions are being used. See #38336 for an example.

Alternatively, extend the phrasings that electron/docs-parser recognizes, and add the smoke tests.

A (possibly non-exhaustive) list of ones which aren't being picked up. There's an upstream issue preventing certain values from being picked up.
