[new release] dune-release (2.1.0)

CHANGES:

### Added

- Add `dune-release delegate-info version` to show the current version as infered
  by the tool (tarides/dune-release#495, @samoht)
- Add `--dev-repo` to `dune-release` and `dune-release publish` to overwrite
  the `dev-repo` field specified in the opam file (tarides/dune-release#494, @samoht)

### Changed

- Use the 'user' option as the fork owner, only attempt to decode the remote URL
  if the user option is not set. (tarides/dune-release#480, @Julow)

### Fixed

- Make `dune-release` not fail in the presence of `~/.dune/bin/dune` (which is present
  when using dune package management)

### Removed

- `dune-release` no longer publishes docs to github pages. Instead, we rely on
  the docs published under `ocaml.org/packages` (tarides/dune-release#499 tarides/dune-release#500, @v-gb @samoht)
