DLT doesn't initialise when using python 3.14 (pendulum >= 3.0.0)

### dlt version

1.20.0

### Describe the problem

I know the readme mentions that python 3.14 support is still 'experimental' but I get the following error when trying to initialise dlt:
```
/opt/homebrew/bin/uv run /src/.venv/bin/python /src/main.py
Traceback (most recent call last):

^^^^^^^^^^^^^^^^^^^^^^^^^^^
