IRM installation fails due to invalid link

[Riztazz]

When trying to install casette-rs using the irm command, the download link is invalid because the semver in the URL contains an extra v.

Broken link:
https://github.com/wowemulation-dev/cascette-rs/releases/download/ngdp-client-vv0.4.3/ngdp-0.4.3-x86_64-pc-windows-msvc.zip

Expected link:
https://github.com/wowemulation-dev/cascette-rs/releases/download/ngdp-client-v0.4.3/ngdp-0.4.3-x86_64-pc-windows-msvc.zip

The problem is because https://github.com/wowemulation-dev/cascette-rs/blob/main/install.ps1#L39 contains a v, and casette-rs release also contains v
