[JENKINS-45547] Unable to add nested conditional steps

I noticed the other day that I am unable to add a conditional build step as a step to a conditional build step (ie. nested conditional build steps).

I've actually been doing nested conditional build steps for over a year using the job dsl plugin without issue.  Sometimes, 4 levels deep.

Steps to reproduce:

1. Create a new freestyle job


2. add a new 'conditional steps (multiple)' build step.


3. click 'add step to condition' and then notice there is no option to add 'conditional steps (multiple)'

No source file or test is named. Start by reproducing the UI flow in Jenkins 2.46.3 with conditional build step 1.3.6, then inspect the conditional-buildstep-plugin implementation that defines the available steps. Done means the “conditional steps (multiple)” option appears when adding a step inside another conditional step and nested configurations can be saved.
