Dist enhancements

Hi, I've made two changes:
* added `Capture::Tiny` to **SEE ALSO** section
* removed explicit `remote = github` from `dist.ini`; that way repository information would appear in `META.*` files and will show up nicely on [MetaCPAN](https://metacpan.org/pod/System::Sub)

This PR is part of my [advent quest](https://questhub.io/realm/perl/quest/547b4202070ccf750d00010e).

Cheers,
Sergey.
