Update tools.yaml

When search hotels with some LLM, the date format shows as bellow
```
**Check-in Date:** April 23, 2024
```
So i update the SQL in tools.yaml to be compatible with following instruction:
```sql
update checkin date to 'April 24,2024' and checkout date to 'April 26,2024' of Best Western Bern
```
