chore: Reducing E2E test sharding (#15192)

* chore: Removing E2E test sharding

* Added back 4 shards for main E2E

* Bump build machines to use 8vCPUs

* Downgrading builds to 2 vCPUs to see time difference

* Reduced shards to 2 to see if flakes are reduced

* Increased E2E vCPUs

* Put builds back to 4 vCPUs since they need it

* Updated E2E suite to use 16 vCPUs and no sharding

* Not running in parallel just to test

* Put back the parallelism

* Get rid of themeBasis warning in test suite

* Skipping another flaky test

* 2 shards

* Update e2e.yml
