Updates GitHub URLs from litebito/airsonic-pulse to
Airsonic-Pulse/airsonic-pulse and GHCR namespace from
ghcr.io/litebito/airsonic-pulse to ghcr.io/airsonic-pulse/airsonic-pulse,
in preparation for the org transfer.
Liquibase changesets, historical release notes (v13.1.0-rc.1.md),
HISTORY.md, intentional upstream-attribution references to
kagemomiji/airsonic-advanced, and the FUNDING.yml / CoC contact email
are explicitly excluded.
