Use gh command to create and add to release

This makes substantial changes to the release workflow, most of
them straightforwardly adapted from corresponding material in the
ripgrep release workflow:

- The biggest change is to use `gh` (the GitHub CLI) instead of
  both the ncipollo/release-action and actions/upload-release-asset
  actions.

- Use outputs instead of artifacts for the information that needs
  to go from the `create-release` job into the `build-release`
  jobs. This eliminates the need for actions/upload-artifact and
  actions/download-artifact.

  Furthermore, since `gh` doesn't require a URL to add files to an
  existing release, there is only one output, the version.

- Split up the "Build archive" step so it doesn't need awkward
  conditional logic inside a single script step. Now the platform
  agnostic part of creating the directory and putting documentation
  in it is one step, followed by steps with `if:` keys for Windows
  and Unix.

  For this, the main differences from how it is currently written
  in the ripgrep workflow are the step titles, the uses of shell
  expansion rather than `${{ }}` interpolation for the environment
  variables, and the omission of checksum files since we are not
  currently generating those.

This notably does not add either of the following to the workflow:

- This does not set `permissions:` for the workflow. It was not set
  before, so the configuration, including in the upstream repo,
  seems not to require it. (Note that this does not imply that the
  configuration in the ripgrep repo doesn't require it.)

- This does try to do anything explicit to take the place of
  specifying `omitBody: true` for ncipollo/release-action. I'm not
  sure what should be done for this, but the current behavior seems
  to produce the same result, and passing `--notes ''` to `gh`
  might go too far. The current ripgrep workflow has no explicit
  argument corresponding to this.
