[Bug]: Overly permissive regular expression range

Nadie ha tomado este issue todavía.

### CLI Version

v5.56.2

### Command

https://github.com/linode/linode-cli/blob/fafe73e1f48a48ab9cbdf9b01f679e041f6bf3fa/tests/integration/stackscripts/test_stackscripts.py#L95-L95

It's easy to write a regular expression range that matches a wider range of characters than you intended. `/[a-zA-z]/` matches all lowercase and all uppercase letters, as you would expect, but it also matches the characters: `[ \ ] ^ _ ``.

Another common problem is failing to escape the dash character in a regular expression. An unescaped dash is interpreted as part of a range. For example, in the character class `[a-zA-Z0-9%=.,-_]` the last character range matches the 55 characters between `,` and `_` (both included), which overlaps with the range `[0-9]` and is clearly not intended by the writer.

### Output

_No response_

### Expected Behavior

[CWE-20

### Actual Behavior

### Steps to Reproduce

## POC
The following code is intended to check whether a string is a valid 6 digit hex color.
```python
import re
def is_valid_hex_color(color):
return re.match(r'^#[0-9a-fA-f]{6}$', color) is not None
```
However, the `A-f` range is overly large and matches every uppercase character. It would parse a "color" like `#XXYYZZ` as valid.

The fix is to use an uppercase A-F range instead.

```python
import re
def is_valid_hex_color(color):
return re.match(r'^#[0-9a-fA-F]{6}$', color) is not None
```

## Recommendation
Avoid any confusion about which characters are included in the range by writing unambiguous regular expressions. Always check that character ranges match only the expected characters.

El issue apunta a tests/integration/stackscripts/test_stackscripts.py en la línea 95; inspecciona allí la expresión regular y su cobertura existente. Verifica que los rangos de caracteres acepten únicamente los caracteres previstos, actualiza la prueba o la expresión correspondiente y ejecuta la prueba de integración asociada.
