fix: correct meta_provider version in release-please manifest (#113)

## Summary

- The release-please manifest tracked `meta_provider` as `0.0.7`, but
the actual version on main is `0.1.0` (set in commit 9cce3f4)
- This mismatch caused release-please to generate PR #103 which would
**downgrade** the version from `0.1.0` to `0.0.8`
- Fixes the manifest to `0.1.0` so release-please generates correct
version bumps going forward

## Follow-up

After this merges, close PR #103 and let release-please regenerate it
with the correct next version.
