Fix typo in StashedOnly function and update documentation link in CON…

…TRIBUTING.md (MystenLabs#18153)

## Description 

This pull request includes two changes:

1. Fixes a typo in the `StashedOnly` function. The variable
`curentWallet` has been corrected to `currentWallet`.
2. Updates the documentation link in the `CONTRIBUTING.md` file to
reflect the correct URL from `sui.docs.io` to `docs.sui.io`.

## Test plan 

**For `StashedOnly` Function:**
- Verified that the function `StashedOnly` works correctly with the
updated variable name.
- Ensured that there are no errors or warnings after the change.
- Manually tested the functionality to confirm that it behaves as
expected with the correct variable name.

**For Documentation Link:**
- Verified that the new link directs to the correct site.
- Checked that the "Edit this page" link works correctly with the
updated URL.
