add URLs to DESCRIPTION

[jameslamb]

👋🏻 Hi, I'm one of the maintainers of {lightgbm} (https://github.com/microsoft/LightGBM).

I'm working on adding some tests there that check that changes to {lightgbm} don't break any libraries that depend on it (microsoft/LightGBM#6734). I might want to propose some changes to {misspi} as a result of looking into test failures from that effort. I did not realize that this project was being developed on GitHub, because there is no mention of this repo in the docs at https://cran.r-project.org/web/packages/misspi/index.html.

This proposes adding links to DESCRIPTION, which will show up on the project's CRAN homepage. Example from https://cran.r-project.org/web/packages/lightgbm/index.html:

That's a result of similar DESCRIPTION content in {lightgbm}: https://github.com/microsoft/LightGBM/blob/d4d6c87db02a146ac6dc04b00f538e02a3b22250/R-package/DESCRIPTION#L42-L43

Thanks for your time and consideration, and for using LightGBM!

Thank you so much for your suggestion and for taking the time to look into {misspi}. I’ve merged the pull request and will update the R CRAN version shortly to reflect these changes. I also want to thank you for maintaining such an excellent package in {lightgbm}—it’s a pleasure to use and integrate with!
