Inaccurate Thrift Installation Instructions on README

### Describe the bug, including details regarding any error messages, version, and platform.

The README currently states:

“If you’re on OSX and use Homebrew, you can instead install Thrift 0.21.0 with brew and ensure that it comes first in your PATH.”

However, since Thrift 0.22.0 was released on May 23, 2025, the Homebrew formula for Thrift 0.21.0 is no longer available by default. As a result, users following the current instructions will not be able to install the required version.

To resolve this, we should either:
1. Upgrade the project to support Thrift 0.22.0 (not available on maven yet), or
2. Update the README to guide users to install Thrift 0.21.0 using brew extract, for example:

```
brew tap-new temp/oldthrift
brew extract --version=0.21.0 thrift temp/oldthrift
brew install temp/oldthrift/thrift@0.21.0
```

### Component(s)

_No response_

Beginne damit, den README-Abschnitt mit den Anweisungen für OSX Homebrew Thrift 0.21.0 zu finden, und überprüfe das im Issue beschriebene aktuelle Installationsverhalten. Kläre, ob das Projekt brew extract dokumentieren oder Thrift 0.22.0 unterstützen wird, und aktualisiere anschließend die README so, dass der dokumentierte Installationsweg für die erforderliche Version funktioniert.
