Render note on referenced attributes by default

[lmolkova]

Currently note is only rendered when attribute is defined in the corresponding group (being rendered) or if (full) mode is used.

It results in:

• notes added on the referenced attributes when they are appliable on the definition
• (full) rendering mode on the tables, but then all the extended attributes are rendered which is not always desirable. so tags are used to prevent it. E.g. here https://github.com/open-telemetry/semantic-conventions/blob/80a2d1a8f70c96c51e541827c7548ba42bb77876/docs/database/mssql.md?plain=1#L17 and in many other db/messaging semconv extensions

It complicates things and I see no good reason to not render note on referenced attributes.
