Fix broken link in zh contribute page

Fixes a broken link in the zh contribute page.

Replaced the category link:
`/category/build-wasmedge-from-source`

with a direct document link:
`/contribute/source/build_from_src`

This aligns the zh locale with the English version and should resolve the CI broken link error.
