Show Homebridge v2.0 Readiness mark also for non-installed plugins
### Describe The Bug

In HB UI v4.66.0, the Homebridge v2.0 Readiness mark is not consistent, with some plugins showing a green check mark or an orange question mark, while others do display a mark:

This is also not consistent with v5.0.0-beta.26, with plugins displaying a mark in v4.66.0, but not in v5.0.0-beta.26:

This is confusing in v4.66.0. Does a plugin with no mark mean that it will not work in HB 2.0? What does the orange question mark not being displayed in v5.0.0-beta.26 mean?
