When an operation fails, suggest checking Known Issues

[zooba]

I'm using the Insiders build of VSC and vscode-python, and some operations are failing because of known issues (most recently this morning, #6990).

As a "naive user", I don't necessarily realise that these are known issues, so I have no idea what the status is.

It would be nice if any failed operation (even if it's my fault, such as misconfigured settings) included a link to a Known Issues page, ideally one that is manually curated to include only the current known issues, rather than forcing me to search through the full issues list (since I may not know the right keywords to find my issue, and will probably fall back on just reporting a new one).

This would help me quickly get a resolution or workaround, or at worst would leave me somewhere with an actionable follow-up.

To be clear, this can totally be a false positive message (at least in Insiders). "Did you expect this to fail? Check our Known Issues at https:.."

I wouldn't expect it if, say, my test run succeeds with failed tests. But if an error causes us to bail out of the test run completely then I need some way to follow up.

Such an operation would have to a manual one, I think testing (discovery or execution) is one of the only few manual ops we now have. The originally linked issue #6990 is also related to testing.

@eleanorjboyd Do you think there're error prompts or other UIs in testing which could make use of this idea? I can't find any, feel to reopen this in that case.
