🩹[Patch]: Update dependabot schedule and pin actions to SHA (#5)

Dependabot now checks for updates daily with a 7-day cooldown period,
reducing noise while maintaining timely security updates. All GitHub
Actions are pinned to specific commit SHAs with version comments for
enhanced security and reproducibility.

## Dependabot Configuration

Updated the schedule from `weekly` to `daily` with a `cooldown` of 7
days. This means Dependabot will check for updates daily but will wait 7
days after a new version is released before creating a PR, helping to
avoid early adoption of potentially unstable releases.

```yaml
schedule:
  interval: daily
cooldown:
  default-days: 7
```

## Pinned Actions

All actions are now pinned to specific commit SHAs with version tag
comments for traceability:

| Action | Version | Commit SHA |
|--------|---------|------------|
| `actions/checkout` | v6.0.1 |
`8e8c483db84b4bee98b60c0593521ed34d9990e8` |
| `actions/configure-pages` | v5.0.0 |
`983d7736d9b0ae728b81ab479565c72886d7745b` |
| `actions/upload-pages-artifact` | v4.0.0 |
`7b1f4a764d45c48632c6b24a0339c27f5614fb0b` |
| `actions/deploy-pages` | v4.0.5 |
`d6db90164ac5ed86f2b6aed7e0febac5b3c0c03e` |
