[branding] updated product version to 36.1.x (#10557)

Given that API 36.1 is "api stable", and we have a `$(TargetFramework)` available.

We normally would also bump the product version to 36.1.x to signify this.

`main` will remain `36.1.99-preview.1.x` for now, however it may need to change to 999.
