ci: fix Dependabot Actions cooldown

[hadrien]

Problem

• Dependabot rejects SemVer-specific cooldown fields for the GitHub Actions ecosystem.
• Invalid configuration blocks dependency update processing.

Solution

• Keep the supported five-day default cooldown for GitHub Actions.
• Preserve uv SemVer cooldowns and dependency commit-message settings.
