`mise use` adding tool options from backend

[jdx]

I thought this was fixed but apparently not

❯ mise use [email protected]
mise Installed executable into /Users/jdickey/.local/share/mise/installs/opentofu/1.6.2/tofu
mise [email protected]  ✓ installed
mise mise.toml tools: [email protected]
❯ cat mise.toml
[tools]
opentofu = { version = "1.6.2", exe = "tofu" }
