chore(release): remove goreleaser (#9918)
### Description
Third try is the charm. See
https://github.com/vercel/turborepo/pull/9905 and
https://github.com/vercel/turborepo/pull/9909 for details.
Additional changes:
- Make sure `turbo` binaries are marked as executable. Since they get
downloaded via `@actions/download-artifact` which strips permissions:
[docs](https://github.com/actions/download-artifact?tab=readme-ov-file#permission-loss)
- Correctly set `os: ["win32"]` for the windows package for
`turbo-windows-${arch}`
### Testing Instructions
Changes from previous PRs: added an e2e test to make sure that the
tarball is installable and the included executable is just that.
