Fix strict type errors in kernel tests: Do not quote integers

Sure there is a better grep but used grep -r "'[0-9]'" core/modules/*/tests/src/Kernel/*

Most seemed to come from migrate keys and others seem to be view keys so those seem fine,

Believe this is good.

Eligible in the beta phase as it's just test cleanup.

Committed and pushed 1b1af634d5 to 11.x and 1df6d0e108 to 10.2.x. Thanks!
