feat: change auto-i18n workflow to run daily instead of weekly (#12899)

### What this PR does

Before this PR:
- Auto i18n workflow runs weekly on Sundays at 00:00 UTC
- Workflow name was "Auto I18N Weekly"

After this PR:
- Auto i18n workflow runs daily at 00:00 UTC
- Workflow name is "Auto I18N Daily"

### Why we need it and why it was done in this way

The following tradeoffs were made:
- More frequent syncs mean more PR noise, but translations stay more
up-to-date

The following alternatives were considered:
- Keeping weekly schedule: translations may lag behind source changes
- Running on weekdays only: skipped in favor of daily for simplicity
