CEP-11 & release v2 roadmap

[jaimergp]

• 1. Prepare menuinst for multiplatform support ceps#8
• 2. Merge cep-devel into main #141
• 3. Add defensive pins for downstream users of menuinst <2. This won't be needed in principle, since menuinst 2 has backwards compatibility. Additionally, conda had those pins already.
• 4. Add recipe and workflows for canary artifacts #144
• 5. Tag v2 alphas as required and test in PRs linked below
  • https://github.com/conda/menuinst/releases/tag/2.0.0a0
  • Test in miniforge: Try menuinst v2 (DNM) conda-forge/miniforge#482
  • Use apipkg to provide compatibility forwarders with v1 #151
• 6. Prepare 2.0 release #158
• 7. Merge the conda PR for the new menuinst support and wait for release
  • Enable support for menuinst v2 (multiplatform shortcuts) conda#11882
    • Passing CI, needs review and discussion about CLI
• 8. Merge the conda-build PR and wait for release
  • add menuinst JSON file validation conda-build#4405
    • Passing CI ✅
• 9. Update conda-standalone accordingly and release
  • Bump to conda 23.11.0 (with menuinst v2) conda-standalone#36
  • update to menuinst 2.0.2, constructor 3.6.0 and conda-libmamba-solver 23.12.0 conda-standalone#51
• 10. Merge the menuinst-cep PR on constructor and release
  • Add cross-platform support for the new menuinst constructor#474
  • constructor v3.6.0 conda-forge/constructor-feedstock#73
