LICENSE and CONTRIBUTING files still mention and link to FlowForge

### Current Behavior

Most of the FlowFuse repositories still call out **FlowForge** and link to `https://flowforge.com` in the LICENSE and CONTRIBUTING files.

NOTE: The LICENSE should still refer to FlowForge as the legal entity

@ZJvandeWeg this may be something you wish to clarify and offer precise wording on before the issue is undertaken?

### Expected Behavior

LICENSE and CONTRIBUTING files: should link to `https://flowfuse.com`

CONTRIBUTING files: should say **FlowFuse** not **FlowForge**

LICENSE files: Should clarify **FlowForge** is the legal entity of FlowFuse
