socket-mode(fix): redact ephemeral tokens and secrets from debug logs

[zimeg]

Summary

This PR replaces values that should be redacted in debug logs - such as the ephemeral bot_access_token used in custom functions and interactor.secret - with [[REDACTED]].

Reviewers

The changes from this branch can be tested with a new app:

$ npm install
$ npm run build  # Build this branch
$ cd ~/bolt-js
$ npm install ~/path/to/node-slack-sdk/packages/socket-mode
$ npm ls
├── @slack/socket-mode@1.3.6 -> ./../node-slack-sdk/packages/socket-mode
$ npm run build  # Build bolt
$ cd
$ slack create example --template slack-samples/bolt-js-custom-function-template
$ cd example
$ npm install ~/path/to/bolt-js
$ npm ls
├── @slack/bolt@3.17.1-customFunctionBeta.0 -> ./../../tools/bolt-js
$ slack run

Then add the included "Sample function" to a workflow and inspect logs for [[REDACTED]] values!

Notes

• Similar changes are applied to both socket-mode@latest on main and the socket-mode@1.3.x branch to backport for Bolt JS.
