chore: group uv updates across Dockerfile, mise, and constraints

[iwamot]

Summary

• Add Dockerfile manager and ghcr.io/astral-sh/uv to the uv group, consolidating all uv version updates into a single PR
• Remove redundant docker group as all Dockerfile images now have specific groups (python and uv)
• Ensures consistent uv versioning across Dockerfile, .mise.toml, and renovate.json constraints
