Fix #227, Switch stubs error

[wtakuo]

In the class Activator method activate, the conditional expression was omitted so that the variable versions is always a list with elements of the form "key - value".

What does this implement/fix? Explain your changes.

Perhaps the cause of issue #227 is that in the following code (activator.mts, lines 1121-1130), the value of Object.keys( availableStubVersions).length is always 1 because the type of availableStubVersions is {[key: string]: string[]}.

          Object.entries(availableStubVersions).forEach(([key, values]) => {
            // Map each value to "key - value" and push to resultArray
            versions.push(
              ...values.map(value =>
                Object.keys(availableStubVersions).length > 1
                  ? `${stubPortToDisplayString(key)} - ${value}`
                  : value
              )
            );
          });

The following is the change in this pull-request.
This makes variable versions always a list with elements of the form "key - value".

          Object.entries(availableStubVersions).forEach(([key, values]) => {
            // Map each value to "key - value" and push to resultArray
            versions.push(
              ...values.map(value =>
                `${stubPortToDisplayString(key)} - ${value}`
              )
            );
          });

I just added a little extension to retain the UI text reduction.
But thanks again for taking the time to setup the dev env and creating this PR.
