xtask: Remove auto-release action

The Github Actions release workflow now uses
https://crates.io/crates/auto-release instead, so we don't need the xtask
implementation anymore.

This reverts (with some minor edits) these commits:
* d8bb47b "xtask: Add auto-release action"
* ad75b2f "xtask: Add util::run_cmd_capture_stdout"
* 910bfc3 "xtask: rename Package::as_str to Package::name and make pub"
