URL: https://github.com/apache/airflow/issues/26984
### Apache Airflow version
main (development)
### What happened
Running pre-commit without installing breeze errors out
```
Traceback (most recent call last):

if sources_hash != package_hash:
UnboundLocalError: local variable 'package_hash' referenced before assignment
```
And to understand the error better, I commented out the exception handling
code.
```
try:
package_hash = get_package_setup_metadata_hash()
except ModuleNotFoundError as e:
if "importlib_metadata" in e.msg:
return False
```
It returned
