Repository: callowayproject/bump-my-version
Base commit: c3d89a3 (image tag)
Issue: Zero-padded version parts are not working It seems that this fix was removed with some refactoring happened in #112. Tried with version 0.20.1 and the following config parameters: ``` current_version = "5.06.0" parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)" serialize = ["{major}.{minor:02}.{patch}"] search = "{current_version}" replace = "{new_version}"

Files to edit

bumpversion/versioning/serialization.py

Approach: Modify the serialization to split format specifiers and apply zero-padding to integer version components. When a component has a format spec like `:02`, we should convert the version value to int and format it with the spec.
