Include `injectable` in library comparison

[adzcai]

Is your feature request related to a problem? Please describe. I just found about this small library injectable that seems to achieve a similar effect to Hamilton.

Describe the solution you'd like Include this in the docs so other people can know about it.

Describe alternatives you've considered I guess this is totally optional.

Additional context It has a pretty different style; the overlap might not be that big.

Thanks @adzcai , we hadn't seen this one.

There's a few other dependency injection frameworks that are similar-ish to injectable, but Hamilton usually hasn't been confused for them. What do you think would be most useful to highlight here?
