Bug: Duplicate Tags in Showcase (JavaScript vs javascript)

[PrasadSanap]

What happened?

The showcase currently displays duplicate tags due to inconsistent capitalization (e.g., JavaScript and javascript). This makes filtering confusing.

Proposed Changes:

• Standardize tag capitalization across all projects.
• Update project.json files to follow a single convention (e.g., lowercase).

Benefits:

• Cleaner tag filtering.
• Better user experience on the showcase website.

Steps to reproduce

1. Open the Showcase page
2. Click on the "Explore All Tags" button
3. Notice that both "JavaScript" and "javascript" appear as separate tags

Where did this happen?
