fix(Languages/pt-br/10_InsertionSort): restore ifElseTest, remove JS tool residue

[xuyua9]

What & Why

The pt-br localization of Languages/pt-br/10_InsertionSort/InsertionSort.sol contains a JavaScript translation-tool fragment where the ifElseTest function body should be. The stray lines are not valid Solidity, and the contract does not compile in its current form:

contract InsertionSort {
    // if else

        if (text.includes('zh')) {
            text = translate(text, 'zh', 'pt-br');
        } else {
            text = text;
        }
    }

This almost certainly came from an automated translation pass that did not skip code blocks.

This PR restores the ifElseTest(uint256 _number) function, matching the root 10_InsertionSort/InsertionSort.sol and the code block already documented in Languages/pt-br/10_InsertionSort/readme.md:

function ifElseTest(uint256 _number) public pure returns(bool){
    if(_number == 0){
        return(true);
    }else{
        return(false);
    }
}

After the fix, the diff (ignoring comments) between the root and pt-br InsertionSort.sol is empty, so the localized contract is functionally identical to the canonical one.

Scope

• Single file: Languages/pt-br/10_InsertionSort/InsertionSort.sol
• +5 / -5 lines (the JS fragment was 5 non-comment lines; the ifElseTest body is also 5 lines plus closing braces).

Type of PR

• Typo(勘误)
• BUG(程序错误)
• Improvement(提升)
• Feature(新特性)

How to verify

solc Languages/pt-br/10_InsertionSort/InsertionSort.sol

should succeed (it currently fails with ParserError on the text.includes('zh') line).
