Minor bug: Incorrect (auto-added?) statement in 282, 287, 288 gimbal_device_id

[Hunter McClelland]

In the gimbal_device_id field for messages 282, 287, and 288 the following statement is added on (somehow):

"Messages with same value are from the same source (instance)."

In these cases, the statement seems incorrect. (In other messages, the same statement seems valid.)

I did a little digging, but can't figure out how/why it is in there. I am not sufficiently familiar with the doc-generation workflow, and it appears to be 'derived'/'appended' by something in the tooling. Maybe something which was fixed/removed, but never regenerated?

I decided to stop digging and report here. But if this would be something valuable for a newbie like me to investigate & solve, please say so and I'll give it a try.

Hi Hunter

Thanks for taking the time to report.

The text is derived from the docs build toolchain and is added if a field as the `instance` attribute set. This is supposed to be added for telemetry messages where a single message can provide data from multiple sources - for example, if you have a battery message, the same message is used for each battery, and the instance ID is used to indicate which battery is associated with the message.

It makes so sense to add these for setter messages. I have removed in https://github.com/mavlink/mavlink/pull/2408
