Proposal for dpgen to use release-please action, making development automated and standardized

[saltball]

I suggest dpgen ( and maybe other deepmodeling projects ) to use release-please(https://github.com/googleapis/release-please) action as dflow do, especially for the version number bumping, CHANGELOG generation and breaking changing warnings.

release-please and conventional commits makes sure developers and users have clear commit history in the future. This action is used by some popular repos like webssh2, bootstrap-vue-3, protobuf.js, react-docgen, starship, cloudquery, npm/cli and etc. See deepmodeling/dflow#35 for details.

Please see Release and CHANGELOG of dflow generated by action-bot.

Looks interesting. @njzjz @AnguseZhang @HuangJiameng any comment?

I don't think this action can be used for projects with different development and releasing branches.
