ci: Reduce test parallelism 

This commit updates the CI workflow to reduce the number of subsets
for running twister tests from 5 to 2 because:

1. There is a lot of overhead in setting up the test environment
   compared to the actual test run time (e.g. it takes 10 minutes
   for set-up and 5 minutes for test run per subset in case of Linux).

2. Windows, the slowest platform, runner has been updated to a more
   powerful 8-core machine.
