feat: added a vesting.md documentaion

[ghost]

Added a vesting.md markdown file that explains the vesting component for protocols looking to use Konoha.

Imagine that you are a protocol that wants to implement Vesting of their token for their team and they open documentation. Will they understand what Konoha can offer and what it cannot?

you fixed the few concere issues I raised but didn't address the bigger picture.

once ready for review, please re-request review

Again, you only addressed the concrete minor issues I raised but not the bigger picture. Closing
