chore: add new release workflow

[jericht]

Copy workflow from https://github.com/OpenJobDescription/openjd-sessions-for-python/pull/67

Verification checklist:

• [x] This repo has all secrets used in the new workflow files
  • [x] CI_TOKEN
  • [x] CODEARTIFACT_DOMAIN
  • [x] CODEARTIFACT_ACCOUNT_ID
  • [x] CODEARTIFACT_REPOSITORY
  • [x] CUSTOMER_DOMAIN
  • [x] CUSTOMER_REPOSITORY
  • [x] AWS_CODEARTIFACT_ROLE
  • [x] AWS_CODEBUILD_RELEASE_PUBLISH_ROLE
• [x] The hatch.toml file does not already have an existing release env
• [x] The pyproject.toml file does not already have a section for configuration python-semantic-release
• [x] The new release workflow files do not unintentionally remove anything in the old release workflow files (e.g. integration tests)
• [x] The CodeBuild projects referenced by the workflow exist in our internal infrastructure account
