Fix Forks badge cursor on project cards (#5397)

[loki106-dot]

Currently, the "Forks" badge on project cards looks clickable (pointer cursor) but does not actually link anywhere.
This can be confusing to users expecting it to open the repository or forks list.

This PR updates the cursor style to use the default (non-clickable) cursor, so the badge no longer gives a misleading impression.

Closes #5397

• Before: pointer cursor over the Forks badge

• After: default cursor over the Forks badge

• Ran bundle exec jekyll serve locally to verify the cursor change.
• Checked that other badges and links remain unaffected.
