Updated the entrypoint script to improve the detection and processing of
custom CA certificates. The script now correctly identifies both regular
files and symbolic links with a '.crt' extension, ensuring that all
relevant certificates are included in the keystore. This change enhances
the robustness of the CA certificate setup process.
