There's a go.mod in in tvix/store/protos, which sets the module path to
code.tvl.fyi/tvix/store/protos.
While this path makes kinda sense, it's currently not possible to `go
get` it from that location, as we serve the cgit interface from there.
Fortunately, `go get` has a mechanism to determine clone URLs for a
given go module path, as documented in https://go.dev/ref/mod#vcs-find.
We simply need to serve a small HTML file at that path, describing the
proper clone URL.
This points the clone URL for code.tvl.fyi/tvix/store/protos to a josh-
provided subtree of just :/tvix/store/protos, which will contain the
root go.mod file.
We need another layer of indirection as nginx can't have an `alias`
directive inside a conditional block (but can have a redirect).
Contrary to https://b.tvl.fyi/issues/299#comment-464, it seems to work
for our usecase. It might become a problem if we actually serve `go.mod`
files in a nested fashion at some point, but let's look at that once we
get there.
Fixes b/299.
