### Who can help?

_No response_

### Information

- [ ] The official example scripts
- [ ] My own modified scripts

### Tasks

- [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [ ] My own task or dataset (give details below)

### Reproduction

I did not manage to recreate the bug consistently, however I had it appear on both windows and linux and on python3.8 and python3.10. 

I lack understanding, why it sometimes works and sometimes throws a syntax error. From my python-understanding, this should fail on all python environments with all transformers versions above `4.27.0`.

in python environment, run
`from transformers import AlbertModel` # or any other model
will **sometimes** lead to an error:
```
module = <module 'transformers' from '.../.venv/lib/python3.10/site-packages/transformers/__init__.py'>
fromlist = ('AlbertModel', 'AlbertTokenizer', 'BertModel', 'BertTokenizer', 'CamembertModel', 'CamembertTokenizer', ...)

        except Exception as e:
>           raise RuntimeError(
                f"Failed to import {self.__name__}.{module_name} because of the following error (look up to see its"
                f" traceback):\n{e}"
            ) from e
E           RuntimeError: Failed to import transformers.models.albert.modeling_albert because of the following error (look up to see its traceback):

.venv/lib/python3.10/site-packages/transformers/utils/import_utils.py:1148: RuntimeError
```

The error ocours due to https://github.com/huggingface/transformers/blob/main/src/transformers/modeling_utils.py#L1832 using an invalid escape sequence and therefore not being right python syntax. 
The fix would be to use `reg = re.compile(r"(.*?)-\d{5}-of-\d{5}")` instead to disable escape sequences and write a plain regex instead.


### Expected behavior

I would expect to be able to import transformer models without it sometimes trowing a RuntimeError.
