Did not work well with path param syntax

[RyoJerryYu]

In AIP-127 , Google introduces a {foo=bar/*} syntax for populating a variable to the URI, that the extracted value would with a bar/ prefix. gRPC-Gateway golang server works well with this syntax.

However, this plugin seems did not support this syntax well.

For example, I have a proto file containing this:

https://github.com/usememos/memos/blob/9612c302c4e897057967112be37f1d4adc0c061c/proto/api/v1/user_service.proto#L25-L29

  // GetUser gets a user by name.
  rpc GetUser(GetUserRequest) returns (User) {
    option (google.api.http) = {get: "/api/v1/{name=users/*}"};
    option (google.api.method_signature) = "name";
  }

And with this plugin, the generated code becomes:

  static GetUser(this:void, req: GetUserRequest, initReq?: fm.InitReq): Promise<User> {
    return fm.fetchRequest<User>(`/api/v1/${req.name=users/*}?${fm.renderURLSearchParams(req, ["name=users/*"])}`, {...initReq, method: "GET"});
  }

Which should be a syntax error near ${req.name=users/*} .
