`BugIndicatingError` default message

[bpasero]

I came across the new BugIndicatingError and wonder whether the default error message should align with the default error message we had before.

Yours:

vscode/src/vs/base/common/errors.ts

Line 263 in 27fc8f7

super(message || 'An unexpected bug occurred.');

Our default:

vscode/src/vs/base/common/errorMessage.ts

Line 45 in 897ab95

return nls.localize('error.defaultMessage', "An unknown error occurred. Please consult the log for more details.");

The default error message is also localized.
