Drone is automatically adding quotes during interpolation when the secret is a multi-line content/value. This automatic quoting messes up use-cases where additional text might need to be included during interprolation. For example,
The interpolation should be smart/context aware that is already in quote and not add quotes.
In fact, If the value happens to be multi-line, the YAML should have it in quotes. Otherwise it should result in parsing error. That is my feedback.
