fix: "attempt to index local 'config' (a nil value)" when running :HttpEnvFile

[valchx]

I have an issue where running the :HttpEnvFile returns an error:

Error executing Lua callback: ...nvim-http-client/lua/http_client/commands/select_env.lua:8: attempt to index local 'config'
(a nil value)
stack traceback:
        ...nvim-http-client/lua/http_client/commands/select_env.lua:8: in function 'select_env_file'
        ...hare/nvim/lazy/nvim-http-client/lua/http_client/init.lua:71: in function <...hare/nvim/lazy/nvim-http-client/lua/h
ttp_client/init.lua:70>

After a quick check, I find that we call config.get() without passing any key.

select_env_file expects to receive the whole config. So instead of calling get, I pass options.
