Update config.example.toml key format example

[oblakeerickson]

Now that we have migrated to v-api in db07e89 we need to update the config.example.toml file to match our new reality.

This commit updates the Local key section and the Cloud KSM section to specify a signer and a verifier.

Addresses part of #368

Thanks for updating this in the docs. We do still support CKMS as a key backend in addition to local keys. For the CKMS option it would look like this:

# Cloud KMS
[[keys]]
kind = "ckms_signer" # Static identifier indicating Cloud KMS
kid = "" # Unique key identifer, that will be used in JWKS
version = 1 # KMS key version
key = "" # KMS key name
keyring = "" # KMS keying name
location = "" # KMS region
project = "" # GCP project containing Cloud KMS

[[keys]]
kind = "ckms_verifier" # Static identifier indicating Cloud KMS
kid = "" # Unique key identifer, that will be used in JWKS
version = 1 # KMS key version
key = "" # KMS key name
keyring = "" # KMS keying name
location = "" # KMS region
project = "" # GCP project containing Cloud KMS

Ah I see. Makes sense you wouldn't just get rid of cloud kms support. Updated my original PR comment too.
