Inline tag handling with nested braces is not working as expected

Given the following test case, our Description doesn't work as expected with nested braces in inline tags.

   /**
     * @uses \phpDocumentor\Reflection\DocBlock\Description
     * @uses \phpDocumentor\Reflection\DocBlock\Tags\Link
     * @uses \phpDocumentor\Reflection\DocBlock\Tags\BaseTag
     * @uses \phpDocumentor\Reflection\DocBlock\Tags\Formatter\PassthroughFormatter
     * @uses \phpDocumentor\Reflection\Types\Context
     *
     * @covers ::__construct
     * @covers ::create
     */
    public function testDescriptionCanParseStringWithInlineTagAndBraces() : void
    {
        $contents   = 'This description has a {@link http://phpdoc.org/ This contains {braces} }';
        $context    = new Context('');
        $tagFactory = m::mock(TagFactory::class);
        $tagFactory->shouldReceive('create')
            ->twice()
            ->andReturnValues(
                [
                    new LinkTag('http://phpdoc.org/', new Description('This contains {braces}')),
                ]
            );

        $factory     = new DescriptionFactory($tagFactory);
        $description = $factory->create($contents, $context);

        $this->assertSame($contents, $description->render());
        $this->assertSame('This description has a %1$s', $description->getBodyTemplate());
    }

首先定位 issue 中展示的 DescriptionFactory 和测试方法 testDescriptionCanParseStringWithInlineTagAndBraces。跟踪描述包含嵌套花括号时 inline {@link ...} 内容的解析方式。当提供的断言通过，同时保留渲染后的内容和预期的 body template 时，即表示完成。
