Infixes Update Not Applying Properly to Tokenizer

### Infixes Update Not Applying Properly to Tokenizer

#### **Description**
I tried updating the **infix patterns** in **spaCy**, but the changes are not applying correctly to the tokenizer. Specifically, I'm trying to modify how apostrophes and other symbols ( `'`) are handled. However, even after setting a new regex, the tokenizer does not reflect these changes.

#### **Steps to Reproduce**
Here are the two approaches I tried:

1️⃣ **Removing apostrophe-related rules from `infixes` and recompiling:**
```python
default_infixes = [pattern for pattern in nlp.Defaults.infixes if "'" not in pattern]
infix_re = compile_infix_regex(default_infixes)
nlp.tokenizer.infix_finditer = infix_re.finditer
```
**Issue:** Even after modifying the infix rules, contractions like `"can't"` still split incorrectly.

2️⃣ **Manually adding new infix rules (including hyphens, plus signs, and dollar signs):**
```python
infixes = nlp.Defaults.infixes + [r"'",]
infixe_regex = spacy.util.compile_infix_regex(infixes)
nlp.tokenizer.infix_finditer = infixe_regex.finditer
```

#### **Expected Behavior**
- The tokenizer should correctly apply the **new infix rules**.

#### **Actual Behavior**
- Changes to **`nlp.tokenizer.infix_finditer`** do not seem to take effect.

#### **Question**
Am I missing something in how infix rules should be updated? Is there a correct way to override **infix splitting**?

Thanks for your help!
