usage is simple, it was working every up to today:

```
sshagent(credentials: ['mrBot_gitlab']){
   pwsh "some git commands"
}
```

The gits ssh-agent is in the path and it was working until the update.

  I have tried to downgrade git to version 2.42.0.windows.2, still the same problem.

  This morning I've also downgraded ssh agent plugin back to 376.v8933585c69d3 and it's working again.

  Ok it seems that git installer is deleting the git from PATH, so now it is working again. Athough better diagnostic message would be appreciated.
