Hello, I've encountered an issue when attempting to setup a network mirror for terraform-switcher when using opentofu as my product. Namely, that it will use my mirror to get the version list, but it will not respect my mirror for downloads.

Describe the solution you'd like

I think I've identified this issue for this. I believe it ties back to how mirrors are set at the product level. For Terraform, it has only the one mirror property, but Opentofu has two mirror properties, one of which is nonadjustable to normal users. To verify it wasn't editable, I went through the parameters lib, and was unable to find any code that allowed for it's editing. It is also not present within the parameters struct. I lastly wanted to see where this download mirror property was being passed into the install property and that is occurring here.

I think two possible solutions could work to resolve this. Either a, making the mirror parameter overwrite the download mirror for tofu as well, or adding in a new parameter that will overwrite that value in the tofu product.

Describe alternatives you've considered

While I'm pretty sure that I identified the issue, I could just be unaware of how to adjust or set that value at a config level, and if anyone who is more familiar with the code-base could help me identify how to do so that would be great.

Hey @frostydknight,

Sorry, yes, this was known when adding the OpenTofu support, the mirror is outright ignored for OpenTofu... the most important thing was not breaking Terraform (with regards to the mirror, at least)..
The fact that OpenTofu then requires two endpoints was less than ideal.
I agree that having two mirror URLs would make sense.. but making it less confusing for Terraform users would be important.

I agree with @MatthewJohn as well:

I am open to anyone here suggesting an elegant solution for this.
