Feature (secrets) : Added Clojars Deploy Token detector

[saurabhb-dev]

###Description:
This PR introduces a new secret detector for Clojars Deploy Tokens.

###Fixes: #1749

###Changes:

• Added ClojarsDeployToken struct and regex to veles/secrets/clojarsdeploytoken.
• Registered the detector in extractor/filesystem/list/list.go.
• Updated scan_result.proto with the new clojars_deploy_token field (ID 76).
• Updated binary/proto/secret.go to handle the new token type.
• Ran make protos to regenerate Go protobuf files.

###Verification:
I have verified this locally using the CLI on Windows.

• Created a test file secret_test.txt with a valid Clojars token.
• Ran ./scalibr --plugins=secrets --result=scan-result.textproto ...
• Confirmed the output contains the detected token:

secrets:  {
  secret:  {
    clojars_deploy_token:  {
      token:  "CLOJARS_64995a98a217600eee9335039621324a5bdabd47faa4cf5d6d8827d10c5f"
    }
  }
}
