[Feature]: New installer type "legacy"

[obuolinis]

What is your feature request?

I'd like to request a new installer type "Legacy". It's to distinguish between the two of KeePassXC Windows installers - they have a main installer, and a legacy one for Windows 7/8, the only difference of their urls is string "LegacyWindows".

Have you tested against the current version?
