[Bug] The naming combination of digits and letters triggers a 701 error.

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

1.3.2

### Describe the bug and provide the minimal reproduce step

```
DROP DATABASE root.db0
CREATE DATABASE root.db0

# statement 1
CREATE TIMESERIES root.db0.t1 WITH datatype=INT32 attributes(K8SlZ=500)

# statement 2
CREATE TIMESERIES root.db0.t2 WITH datatype=INT32 attributes(K8SlZ='500l')

# statement 3
CREATE TIMESERIES root.db0.t3 WITH datatype=INT32 attributes(K8SlZ=500l)
```

### What did you expect to see?

The above three statements should all execute successfully.

### What did you see instead?

Statement 1 and Statement 2 executed successfully, but Statement 3 returns the **error**: Msg: 701: 500l is illegal, identifier not enclosed with backticks can only consist of digits, characters, and underscore.

### Anything else?

Dear IoTDB team, upon reviewing the IoTDB software documentation, `500l` should not be a keyword and meets the identifier naming rules, as it is a combination of digits and letters. However, in the attributes as a value, it requires backticks for successful creation. If it is a bug, please mark this issue as "bug". Thank you!

### Are you willing to submit a PR?

Commencez par reproduire les trois instructions CREATE TIMESERIES de l’issue et suivre la façon dont les valeurs d’attribut sont analysées, en vous concentrant sur la valeur non quotée 500l. Le travail est terminé lorsque l’instruction 3 réussit comme les instructions 1 et 2, avec un test de régression couvrant la valeur composée de chiffres et de lettres.
