docs: a2a-sdk[all] installation command in Readme

[Lancetnik]

MacOS doesn't support commands like pip install package[extra] without escaping. Other installation commands are written like pip install "a2a-sdk[extra]", for this reason. I have just fixed this issue.

Summary of Changes

Hello @Lancetnik, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a minor but important documentation issue in the README.md related to the installation of the a2a-sdk with all its extras. The change ensures that the provided uv add and pip install commands are correctly formatted with quotes around the [all] extra, resolving compatibility problems on operating systems like macOS where unescaped brackets can lead to command execution errors. This improves the user experience by providing universally functional installation instructions.

Highlights

• Documentation Update: Corrected the installation commands for a2a-sdk[all] in the README.md to properly quote the extra dependency group.
• Cross-Platform Compatibility: Ensured that the uv add and pip install commands for the 'all' extras are compatible with macOS and other systems that require escaping for bracketed expressions in shell commands.

Code Review

This pull request correctly fixes an issue in the README.md where installation commands with extras were not quoted, which can cause issues in some shells. By adding quotes to the a2a-sdk[all] installation commands for both pip and uv, you've improved the documentation's clarity and reliability for all users. This change also makes the command consistent with other extras in the table. The change is well-executed and I have no further suggestions.
