We have a hard-coded list of countries inhttps://github.com/coder/coder/blob/main/site/src/pages/SetupPage/countries.tsx

This unfortunately means that the Go code in coder/coder doesn't have an easy way of utilizing it.

Proposed solution

Generatecountries.tsx from Go code. This would entail modifyingcountries.tsx to Go syntax and using code generation to writecountries.tsx.

This should be a relatively small lift as we have extensive code generation already in place. It could possibly be generated byscripts/apitypings.
