[JENKINS-76224] NullPointerException when triggering a build

When triggering a build, the build immediately fails with the following exception:

java.lang.NullPointerException

	at java.base/java.util.Objects.requireNonNull(Objects.java:233)

	at PluginClassLoader for scm-api//jenkins.scm.api.SCMFileSystem.of(SCMFileSystem.java:213)

	at PluginClassLoader for workflow-cps//org.jenkinsci.plugins.workflow.cps.CpsScmFlowDefinition.create(CpsScmFlowDefinition.java:120)

	at PluginClassLoader for workflow-cps//org.jenkinsci.plugins.workflow.cps.CpsScmFlowDefinition.create(CpsScmFlowDefinition.java:72)

	at PluginClassLoader for workflow-job//org.jenkinsci.plugins.workflow.job.WorkflowRun.run(WorkflowRun.java:317)

	at hudson.model.ResourceController.execute(ResourceController.java:101)

	at hudson.model.Executor.run(Executor.java:460)

Finished: FAILURE

There needs to either be success, or there is an error here that isn't being handled.

environment

```
jenkins-2.528.1-1.1.noarch

v4236.v3cb_7ea_578c1f
```

Start at org.jenkinsci.plugins.workflow.cps.CpsScmFlowDefinition.create, using the reported lines 120 and 72, then trace the call into jenkins.scm.api.SCMFileSystem.of at line 213. Reproduce the build trigger with Jenkins 2.528.1 and the listed workflow-cps version. Done means the trigger no longer ends in an unhandled NullPointerException and either completes or reports an error.
