feat(StakeVault): add withdraw function and improve documentation
This commit introduces new functions for keeping track of the total amount staked and implements a function to check the available amount of tokens that can be withdrawn. Users are able to withdraw tokens that are not commited to stake by calling the withdraw functions. These changes enhance the overall usability and flexibility of the StakeVault contract.
