govern and simple-voter import fails due to old smart-wallet dependency

[secretshardul]

Anchor version- 0.23.0

govern import breaks when smart-wallet v0.9.0 is compiled. Importing smart-wallet directly also gives the same error-

The latest smart wallet version is 0.10.1, so we should bump up.

Edit- Addressed by #149. Merge is blocked due to a failing test
