ci: Fix Linux jobs on Ubuntu 26.04 runners - #6920

Conversation
ubuntu-latest now resolves to Ubuntu 26.04, where Java 25 is the default JDK and no Swift 6.0 toolchain is published. Set up Java 17 in the Linux jobs that build or lint Java, since Gradle 8.13 can't run on Java 25. Install Swift 6.4.1 for SwiftLint, the first release with Ubuntu 26.04 toolchains.

📜 Description
GitHub's
ubuntu-latestrunners moved from Ubuntu 24.04 to 26.04, which breaks two things in CI:Java 25 is the default JDK on 26.04.
yarn buildrunsbuild:replay-stubs(./gradlew jar), and Gradle 8.13 can't run on Java 25:Fix: set up Java 17 (Temurin, same pinned
actions/setup-javaas the other workflows) in the Linux jobs that build or lint Java and had no Java setup:buildandtest.yml: Lint, Build, Bundlesample-application-expo.yml: Build webSwiftLint can't run on Ubuntu 26.04. The Lint job first fails at
swiftly install 6.0(No release toolchain found matching 6.Optional(0)), because Swift 6.0 has no 26.04 toolchain. Moving to Swift 6.4.1 (the first release published for 26.04) gets past that, but then SwiftLint 0.63.2's Linux binary fails withlibxml2.so.2: cannot open shared object file: 26.04 ships libxml2 2.15 (libxml2.so.16), and nothing provideslibxml2.so.2. SwiftLint's fully static binary is still marked experimental.Fix: pin only the Lint job to
ubuntu-24.04, keeping Swift 6.0 and the current SwiftLint setup.The macOS jobs are unaffected and unchanged.
💡 Motivation and Context
Every PR fails Build & Test / Lint, Build & Test / Build and Sample Application Expo / Build web since the runner image change. The last green
mainrun was onubuntu-24.04(20261012.601); the first failing run was onubuntu-26.04(20261015.610). Example: https://github.com/getsentry/sentry-react-native/actions/runs/39566567140💚 How did you test it?
