There's two main reasons for this implementation detail change:
1) got has moved onto the next major version and drops support for node versions this
   package must continue to support. they have no plans to continue to ship features
   and bugfixes on the v8 release line.
2) axios has a significantly reduced bundle size compared to got v8.x.

This swap also removes the need for a couple ts-ignore pragmas. But, since axios' typings
are much looser than got's, it also means the checks are less valuable. Still, it seems
like the right tradeoff.
