feat: do some trivial adaptions for blender 4.2 LTS

- add blender_manifest.toml
- add a removal note for bl_info in __init__.py.
- it doesn't mean that this plugin now can be used in blender 4.2. I just add some trivial changes which do not break current compatibility to reduce migration work in future.
