[Task] Add a dev tag to main development branch after release branch created

Background

Since we adopted release branches last year where we create our tags corresponding to each release on the commits of the release branch. The version that each of our packages reports on the main (development) branch reports the last tag that appeared in the history of this branch (which could be old, and is likely to not be the last release.). We're using versioneer to manage the version which does this based on the tags it can find. Adding a tag to the main branch corresponding to the start of development of the upcoming release enables us to continue using versioneer and the release branches.

An alterntaive option we considered is merging the release branch back into main, which would achieve a similar result in principle, however in practice if the development branch diverges, we'll end up with merge conflicts and changes that we don't want to merge back in to the development branch.

Description

Release n+1 will be tagged with vYY.MM.dev0 This will be applied to the commit on the main branch where the release branch was created from.

Tasks

• Update Workflows in all repos to ignore dev tags
  • https://github.com/NVIDIA-Merlin/core/pull/311
  • https://github.com/NVIDIA-Merlin/dataloader/pull/143
  • https://github.com/NVIDIA-Merlin/models/pull/1081
  • https://github.com/NVIDIA-Merlin/NVTabular/pull/1812
  • https://github.com/NVIDIA-Merlin/systems/pull/342
  • https://github.com/NVIDIA-Merlin/Transformers4Rec/pull/695
  • https://github.com/NVIDIA-Merlin/Merlin/pull/964
• Create v23.05.dev0 tag (pointing at commit where release-23.04 branched from)
  • core
  • models
  • dataloader
  • Transformers4Rec
  • NVTabular
  • systems
  • Merlin
• Update release branch creation script/process to add empty commit after branch is created
  • This ensures that we don't have two tags pointing at the same commit. (Versioneer (git describe --tags) doesn't have well defined behaviour for which tag to return))
  • Current release process docs: https://docs.google.com/document/d/12Z8tX94J_TrkGJbSxrOAs-zXqgdTrH5XvXgXEhznTko/edit?usp=sharing
