Refresh PHPStan baseline for php-http/cache-plugin update

A recent php-http/cache-plugin release moved handleRequest() from
CachePlugin to the new @internal AbstractCachePlugin parent. Update the
existing argument.type ignore to the new class name and add a baseline
entry for the resulting method.internalClass error on the same call
site, so CI unblocks. Long-term fix is to stop calling the internal
parent method, tracked separately.
