Jupiter now supports unstaked JUP tokens

The Solana ecosystem DEX Jupiter has made two governance mechanism optimizations based on user feedback. Firstly, users are now allowed to partially cancel their JUP stake and still be able to vote while retaining a portion of their stake. Additionally, in order to give users more time to understand proposal content, a timer has been added to the voting page, which requires a few minutes of waiting after opening a proposal before being able to vote.
