Issues

• Some references to deprecated ebytesxxx FHE primitive types are still present in some typescript files.
• In every export const decryptXX = async (handle: string): Promise<bigint> => { function documentation, the first param is wrongly named a instead of handle

Solution:

• Remove all references of deprecated ebytesxxx FHE primitive types.
• Rename a into handle in export const decryptXX functions documentation.
