Issue:
$reader->setTestAutodetect() not usefull when php version > 8.1
This is:

```
- [x] a bug report
- [ ] a feature request
- [ ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)
```

### What is the expected behavior?
To not force the user to set autodetect to false when detected php version is >= 8.1
Simply keep it to false or never set it .


### What is the current behavior?
Forced to set false in order to not have problems with deprecation notices

### What are the steps to reproduce?

Set true with php >= 8.1 version

```php
<?php

require __DIR__ . '/vendor/autoload.php';

// Create new Spreadsheet object
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

// add code that show the issue here...
```
If this is an issue with reading a specific spreadsheet file, then it may be appropriate to provide a sample file that demonstrates the problem; but please keep it as small as possible, and sanitize any confidential information before uploading.

### What features do you think are causing the issue

- [ x] Reader
- [ ] Writer
- [ ] Styles
- [ ] Data Validations
- [ ] Formula Calculations
- [ ] Charts
- [ ] AutoFilter
- [ ] Form Elements

### Does an issue affect all spreadsheet file formats? If not, which formats are affected?
any software

### Which versions of PhpSpreadsheet and PHP are affected?
>= 8.1


Pull request:
Breaking Change - 3 Defaults
Fix #4092. Change default value for Csv Reader autodetect line endings. Prior behavior can be enabled via `setTestAutodetect(true)`.

Change default value for Html Writer "better boolean" logic. Prior behavior can be explicitly enabled via `setBetterBoolean(false)`.

Change default for Xlsx Writer forceFullCalc option. Prior behavior can be explicitly enabled via `setForceFullCalc(null)`.

This is:

- [ ] a bugfix
- [ ] a new feature
- [ ] refactoring
- [ ] additional unit tests
- [x] more sensible default values

Checklist:

- [x] Changes are covered by unit tests
