Go backend performs very poorly for private modules with many versions

[connorszczepaniak-wk]

Running mise use -v -g go:github.com/company/private@latest takes an extremely long time when company/private has >1000 releases. It looks like when a module isn't proxied (because it's private), mise falls back to go list for every version, and this takes a very long time.

Could mise just directly call go install github.com/company/private@latest? latest is directly supported by go install with no need to list all versions, and go install also supports installing at a version using the same syntax. Why does mise need to list all versions before installing?
