* Update keypair configuration output
While going through the tutorial to start a validator I noticed that the output I received from running...
```
solana config set --keypair ~/validator-keypair.json
```
...different from the output I was seeing. Wondering whether the docs are out of date I thought I'd propose an update to the docs just in case.
(cherry picked from commit 02157f4753)
* Update docs/src/running-validator/validator-start.md
(cherry picked from commit de76adbdf3)
