PR opened in draft as I haven't implemented the changes for the Licenses field yet. I'm still working on creating a hidden field that submits a value of "Proprietary" when the Licenses field is hidden.

Thanks for this @CWestICL. Looks like a good start. One question, and bear with me here, but how does it work? The logic in the AutosaveSoftwareLicenses function makes sense to me and I guess the form is being re-rendered when the switch is toggled but what's the mechanism behind this?

For any further changes could you create PR's against the closed-source-ui branch, same as we did with the imperial-home-page branch. We'll need to shut this one as we shouldn't be putting things into main of this fork.

Ah my bad, I'll reopen this PR with a new branch.

As for the mechanism behind what I've done so far, I think the SoftwareInformationForm component is using some react-hook-form functionality to watch for any changes made to the form and re-render accordingly. Each time the switch is toggled it updates the formData.closed_source value which I've then used an if statement to hide/show the relevant fields.

I haven't actually implemented the AutosaveSoftwareLicenses logic yet as I haven't wrapped my head around how exactly the License values are saved to the Software item in the database. I'm thinking that I can use the if statement to hide the Licenses field like I've done the others but I also need to find a way to inject the "Proprietary" value into the form itself.
