Description Of Change

Accept queryLabel as query option (open to alternate names, like loggingLabel or just label). Extremely useful for labeling queries when query logging is turned on. For example, when I have query logging turned on and I hit an endpoint in one of my applications, a dozen or more queries may show up in the logs. This allows me to provide a name/label so I can quickly jump to the code that produced a given query.

Seems like a nice feature to add. Could you add a test for when the query has been executed as well (the afterMsg). And maybe we should add something for when queryName is '' so that you don't get an additional empty character at the start.

Thanks for this PR!

About the documentation, you can open a PR on the website repo to add it to the logging section; https://github.com/sequelize/website/blob/main/docs/getting-started.mdx#logging but since it's also mentioned in the types it should be reflected in the API reference as well.
I would however appreciate it if it's added to the constructor docs, just like the other options.
