[Test] Remove ASYNC translog durability in N-2 bwc upgrade tests (#121278)

When adding support for upgrading closed indices in 
N-2 version, I randomized the Translog.Durability setting 
of the closed index with the aim to test the 2 phases 
closing process.

This caused at least 1 test failure on Windows with the 
index being closed and the cluster upgraded before the 
synchronization of the translog had a chance to be 
executed. I think this cause the engine to be reset on 
the replica that is promoted as a primary, causing the 
loss of the operations that were not yet persisted.

Closes #121257
