Make the Adoptopenjdk package type look at the Temurin repo first for latest assets (#522)

* Make the Adoptopenjdk package type look at the Temurin repo first for latest assets

* Address Copilot code review comments

- Use strict equality (===, !==) instead of loose equality (==, !=) for all comparisons
- Properly handle caught errors with instanceof type narrowing before accessing properties
- Only fall back to legacy AdoptOpenJDK for specific version-not-found errors
- Rethrow unexpected errors to avoid masking real issues (network failures, rate limits, etc.)
- Fix error message check to match actual error text ('No matching version found')
- Remove unnecessary undefined check since method return type is never undefined
- Add @internal JSDoc annotation to TemurinDistribution.findPackageForDownload()
- Update tests to properly mock Temurin lookup failures for fallback behavior testing
- Rebuild dist files

* Always fall back to legacy AdoptOpenJDK but log all Temurin failures

- Change error handling to gracefully fall back for all errors, not just version-not-found
- Log version-not-found errors as notices with migration guidance
- Log other Temurin failures as debug messages for troubleshooting
- Improves resilience: users always get a result even if Temurin API has issues
- Maintains visibility: failures are still logged for debugging
