Don't reset upper bounds (elastic#135226) (elastic#135303)

Transport version upper bounds are currently set to their values from
upstream main whenever no new definition is detected. However, this
is like a partial merge of upstream, and produces broken state files.
This commit temporarily comments out resetting until a more robust
solution is built.
