[ci] fix symfony serializer deps in ci

When running serializer tests in Symfony <= 5.3, composer attempts to use `symfony/[email protected]` (The latest version at the time of this PR) which conflicts with `symfony/property-info` `<5.4`. This in turn causes our tests to fail due to an uninstallable set of packages.

As a work around, until something better comes along, adding `symfony/serializer-pack:*` as an extra test dependency allows lesser version of `serializer-pack` to be used in the test without conflict with its underlying packages.
