fix(uv): drop powerpc64 support to fix latest version downloads

Before this PR we would index all of the available binaries and it would
fail in the case if the `sha256` file is not found. It seems that this
is the case for the `powerpc64`. In order to work this around, we just
drop support for that particular platform.

Whilst at it, bump the uv version.

Fixes #3676.
