Update `tar` development dependency to 7.4.3
The latest major version of tar contains type definitions within the package itself. This removes the need to install the separate @types/tar package.
It looks like this is breaking the typings used by minizlib.
I believe this is broken because the owner of minizlib needs to approve and merge this PR:
https://github.com/isaacs/minizlib/pull/31
I was looking at opening a PR to enable esModuleInterop actually. That would solve this issue and other future subtle ESM/CommonJS interoperability issues which will become more common as packages move to ESM only.
I believe we can do this now. There is a failing test which I believe to be unrelated to the upgrade tho. Closing in favor of https://github.com/sass/embedded-host-node/pull/311
