docs: move composer install instructions to setup/install.md (#75)

[EmiFunes91]

This pull request addresses issue #75 by moving the Composer installation instructions
from architecture/using-composer.md to setup/install.md, where they are more appropriately placed.

Changes made:

• Relocated the composer create-project block and related instructions.
• Updated architecture/using-composer.md to include a reference link to the new location.
• Ensured Markdown formatting consistency and professional tone in both files.

Benefits:

• Improves discoverability and structure of installation steps for new users.
• Aligns with best practices for documentation organization.
• Avoids duplication and makes maintenance easier.

Closes #75

Thanks for your interest in improving our docs @EmiFunes91. It does appear, however, that you have used an AI-assisted tool to generate these edits that unfortunately do not fit with our documentation structure. Please see the comments below to better implement these changes.

Hi @bennothommo, thanks again for your detailed feedback.

I've now implemented all requested changes:

Removed the unnecessary markdown code block tag.

Moved both the Installing Winter via Composer and Configuring Winter sections to setup/installation.md, just below the Web-based Installation.

Removed the previously added setup/install.md file, as suggested.

All changes have been cleaned up and verified, and the conversations have been marked as resolved.

I’ve also responded to each individual comment and marked them as resolved after applying the requested changes.

Let me know if there's anything else to adjust — otherwise, it's ready for final review. Thanks again for the opportunity to contribute!

Minor update: Changed my-winter-site to my-project to match the official installation guide at https://wintercms.com/install. Thanks again!

@EmiFunes91 thanks for your efforts, but unfortunately I cannot accept this PR in its current form, and it appears that you are using AI to make these edits, and it is not understanding the context of my suggestions. We'll go down a different route to implement the changes required to satisfy #75. Thanks again.

Understood, thank you for your time and feedback.
I appreciate the opportunity to contribute and I understand the importance of aligning with the project’s structure and expectations.
I’ve learned a lot from this process and hope to support the Winter CMS project again in the future.
