Exiting ddev ssh results in a reported error even though there is none

[rfay]

Describe the bug

ddev ssh returns the result code of the previous command on exit, instead of a success.

To Reproduce
$ ddev ssh
$uid_501@955b035eda20:/var/www/html$ kdkdkd
bash: kdkdkd: command not found
uid_501@955b035eda20:/var/www/html$ exit
exit
Failed to ssh d8git: exit status 127

Expected behavior

I'm pretty sure ddev ssh should always return success on exit

Additional context

This pollutes the Sentry logs quite a lot, and is completely unnecessary.
