[SUBS] Update currents to use playwrights fully parallel mode when possible

[elvijsTDL]

As the avarage run duration is starting to creep to about 20-30 minutes I decided to increase the current parallelization to lower test run times

Playwright by default parallelizes tests per file ( it does not take into account the total test count , just runs each file on a seperate worker) , to enable splitting the bigger test files and running each test in parallel from a single file fullyParallel mode has to be enabled which is currently not supported by Currents

This results into the test run running as expected , but most of the results get overwritten

About 80 test cases were run in this workflow , only 20 are saved in currents because the playwright shards overwrite each other

Currents support team said that this functionality should be done in 2-3 weeks, but for now as a work around I will be splitting each of the test files into smaller files so they don't clash together and overrwrite each other , once the feature is released I will revert to the file structure which more closely represents page object model
