Reinstall/remove menu only occurs when installing the same version/installer

#### Description:

The current implementation of the installer only displays the reinstall and remove dialogue when explicitly reinstalling the exact same version of the installer.

Suggesting improvement, and to help user further, by enabling once BHoM is installed (any version) providing a similar dialogue that states "Reinstall"- but with more details about which version.

i.e. Which version user is currently on. And then which version they are upgrading/downgrading to (or simply reinstating)

The issue names no files or tests. Start by locating the installer code that decides when the reinstall/remove dialogue appears, then trace how the installed and target versions are obtained. Done means the dialogue appears for any installed BHoM version and identifies the current and target versions for reinstall, upgrade, and downgrade, while preserving the existing same-version behavior.
