ssh version output in stderr
Generally Linux commands print their version on stdout, for example
git --version or python --version. But not ssh. ssh -V prints output to stderr.
To test it you can do the following:
git version on stdout
> git --version 2> error 1> output
> cat output
git version 2.51.0
ssh version on stderr
> ssh -V 2>> error 1>> output
> cat error
