Commit efd07ac5cd0fd43b4abde7f9e42d90272f9e6063

Key changes:

1. Updated the reference link in the rusttls.md file to point to the correct GitHub repository.
2. Updated the reference link in the wasi_crypto.md file to point to the correct GitHub repository.

Potential problems:

1. In the rusttls.md file, the reference link was updated correctly to point to the wasmedge_rustls repository. This seems to be a straightforward fix with no apparent issues.
2. In the wasi_crypto.md file, the reference link was updated correctly to point to the wasi_crypto repository. This also appears to be a straightforward fix with no apparent issues.

Overall, the proposed changes seem to be correct and consistent with updating the reference links to the correct GitHub repositories for both plugins. The patch appears to address the issue of fixing the reference links effectively.
