feature #1029 Allow psr/cache 2.0 as well as 1.0 (johnnoel)

This PR was merged into the 3.4.x-dev branch.

Discussion
----------

Updates the composer.json file to allow for `psr/cache` version 2.0 which is the default installed alongside frameworks like Symfony 5.3. As far as I can tell it's API compatible and the test suite passes with 2.0 installed.

Could also extend the versions to allow 3.0 (which is what projects like `doctrine/persistence`) do but not sure what 3.0 brings to the table.
