refactor: Reformat tsconfigs for consistency (2nd round) (#3295)

This pull request makes minor formatting adjustments to the
`tsconfig.karma.json` file, expanding the `types` and `include` fields
into multi-line arrays for improved readability. No functional changes
were made.[^1]

[^1]: It also is a follow-up to #3293 – I missed a spot.
