chronos is available in the Nim Playground

This doesn't seem to be true at the moment, yet it is in https://github.com/PMunch/nim-playground/blob/efae1579cf9ad486fa91daf8833fbd33e001da91/docker/packages.nimble#L23

I get this output for Nim v2.0 and latest:

Hint: used config file '/playground/nim/config/nim.cfg' [Conf]
Hint: used config file '/playground/nim/config/config.nims' [Conf]
...................................................................................................................................................Killed

and this output with v1.6.14:

Hint: used config file '/playground/nim/config/nim.cfg' [Conf]
Hint: used config file '/playground/nim/config/config.nims' [Conf]
..........................................................
/usercode/in.nim(1, 8) Error: cannot open file: chronos

(I previously opened this issue in chronos repo https://github.com/status-im/nim-chronos/issues/436)
