docker: module 'http.router' not found

Hi I have an error when trying to run a simple server in docker with tarantool/tarantool How to reproduce:

put code from https://www.tarantool.io/en/doc/latest/book/app_server/cookbook/#http-server-lua to test.lua
```
#!/usr/bin/env tarantool
```

local function handler(self) return self:render{ json = { ['Your-IP-Is'] = self:peer().host } } end

local server = require('http.server').new(nil, 8080) -- listen *:8080 local router = require('http.router').new({charset = "utf8"}) server:set_router(router) router:route({ path = '/' }, handler) server:start()


+ run `docker run --rm -t -i -v "$(pwd)"/test.lua:/opt/tarantool/test.lua tarantool/tarantool:2.8  tarantool /opt/tarantool/test.lua`

```bash
LuajitError: /opt/tarantool/test.lua:8: module 'http.router' not found:

        no file '/opt/.rocks/share/tarantool/http/router/init.lua'
        no file '/.rocks/share/taranto
fatal error, exiting the event loop

idk where to place the issue, this is duplicate https://github.com/tarantool/http/issues/139

tarantool / docker
