google_checks.xml: remove xpath suppression and false-positive indentation violations for block codes
I have read check documentation: https://checkstyle.org/checks/misc/indentation.html
I have downloaded the latest checkstyle from: https://checkstyle.org/cmdline.html#Download_and_Run
I have executed the cli and showed it below, as cli describes the problem better than 1,000 words

Detected at https://github.com/checkstyle/checkstyle/issues/14294

In [google_checks.xml](https://github.com/checkstyle/checkstyle/blob/master/src/main/resources/google_checks.xml), [Indentation](https://checkstyle.org/checks/misc/indentation.html) module gives false-positive error for following type of blocks:

```
{
  int x = 99;
}
```


**Example:**

```java
/** Test... */
public class Test {
  private static void indentationIssue(int condition) {
    { // line 4, false-positive
      System.out.println("True");
    } // line 6, false-positive
  }

  { // good, no violation
    System.out.println("False");
  } // good, no violation

    { // line 13, expected
      System.out.println("False");
    } // line 15, expected

  class Inner {
    void test() {
      { // line 19, false-positive
        System.out.println("True");
      } // line 21, false-positive
    }
  }
}
```

@romani suggested to use suppression to suppress these false-positives until we find a way to fix it at: https://github.com/checkstyle/checkstyle/issues/14294#issuecomment-2408353743

The suppression is:

```xml
    <module name="SuppressionXpathSingleFilter">
      <property name="checks" value="Indentation"/>
      <property name="query" value="//SLIST/SLIST"/>
    </module>
    <module name="SuppressionXpathSingleFilter">
      <property name="checks" value="Indentation"/>
      <property name="query" value="//SLIST/SLIST/RCURLY"/>
    </module>
    <module name="Indentation">
      <property name="basicOffset" value="2"/>
      <property name="braceAdjustment" value="2"/>
      <property name="caseIndent" value="2"/>
      <property name="throwsIndent" value="4"/>
      <property name="lineWrappingIndentation" value="4"/>
      <property name="arrayInitIndent" value="2"/>
    </module>
```

Adding this suppression will suppress all indentation violations for above mentioned type of blocks whether they're correct or not but we need to use it till we find a fix.

---

As part of this issue, we need to find a way to fix this false-positive and remove the suppression. 

I am on it
