Trying to set up blue ocean pipeline with git repo in format `git@host:user/repo.git` throws exception and the flow gets stuck.

Could be related to ~~JENKINS-70379~~.

I am running latest jenkins version (2.389) through docker and latest blueocean plugin (1.27.1) installed through plugins.txt

There are actually two different exceptions.

Exception when I just paste in the repo address and javascript automatically triggers some background action.
Different exception (different class not found) when I click on the "Create pipeline" button

I used find to look for `jsch*` in file system, and it is not there when installing blueocean plugin. I tried adding jsch to plugin list manually (even though you are not supposed to) and it did not help either.
