Bruno UI and CLI Reporters can expose secret variables

I have checked the following:

Describe the feature you want to add

The shown example is the Bearer Auth example from the testbench repo, but I've marked the bearer_auth_token as private. The UI still shows the token in the timelime tab. Same for the json export, that you can generate using the cli --format json option. This can expose your secrets if you are live-sharing your screen, share a screenshot or the exported report without manually hiding it. So I suggest, after the request is finished, check the whole output, including every header (request and response), response data, assertion/script output, etc..., for exact (or case-insensitive?) matches and replace them with something else, like a fixed number of asteriks or the variable name.
