Translog: remove unneeded Versions.readVersion & Versions.writeVersion

These calls were introduced in pr #6149 as a backward compatibility layer for the previous value of `Versions.MATCH_ANY`. This is not needed as the translog never contains these values. On top of that, the calls are not effective as the stream the translog used is effectively not versioned (versioining is done on an item by item basis)
