Re-balance the workload of plugintests

I don't think we need this and you actually cannot "rebalance" them, as we're using matrix build, all the plugin tests of each plugin are run parallelly , no mater which workflow they belong to

The time it costs only depends on the version numbers of the plugin test and the test itself
