Update installation instructions to prevent confusion with similarly named package

[clauses3]

Issue

Currently, installation instructions may lead to confusion due to existence of similarly named package.

Issue:

• The command pip install aider installs an unrelated recently added package (https://pypi.org/project/aider/)
• This package appears to be typosquatting and may pose risk to users

Suggestion:

• Add a warning note about the potential confusion with similarly named package

This change will help prevent users from accidentally installing the wrong package and ensure they get the intended functionality.

I have an open request to take over the unused aider package name.
