[new release] opam-monorepo (0.3.6)

CHANGES:

### Added

- Display warning when a package to be locked is missing a `dev-repo` field and
  is being skipped because of it (tarides/opam-monorepo#341, tarides/opam-monorepo#362, @kit-ty-kate, @Leonidas-from-XIV)
- Add option `--keep-symlinked-dir` to preserve symlinks in `duniverse/`, which
  can be useful for local development. (tarides/opam-monorepo#348, tarides/opam-monorepo#366, @hannesm,
  @Leonidas-from-XIV)

### Changed

- Canonicalize the URLs of the OPAM `dev-repo` fields to be able to detect more
  semantically equivalent URLs, this should reduce the risk of build failures
  due to duplicate code pulled (tarides/opam-monorepo#118, tarides/opam-monorepo#365 @TheLortex, @Leonidas-from-XIV)

- Simple the error message printed when dependencies don't use dune as their
  build system. The opam-0install diagnostic message is no longer printed in
  this case and the message has been reformatted and reworded to make the
  salient information easier to see. (tarides/opam-monorepo#384, @gridbugs)

### Fixed

- Error in case where multiple packages with different dev-repo fields would be
  placed in the same duniverse directory (tarides/opam-monorepo#377, @gridbugs)

- Fix a failure when using opam-monorepo with an opam 2.2 root
  (tarides/opam-monorepo#379, @kit-ty-kate)

- Fix assertion failure when prefix of "lock" subcommand is used (tarides/opam-monorepo#381,
  @gridbugs)

- Treat packages without build commands as virtual only if also lack install
  commands, as some non-virtual packages might only have install commands.
  (tarides/opam-monorepo#376 @Leonidas-from-XIV, @gridbugs)
