[chore] Add display names to encoder extensions (open-telemetry#45647)

cormah · ChrsMark · cormah · commit e2611d919772 · 2026-01-28T23:08:04.000+01:00
**Description** Uses the new [display_name](open-telemetry/opentelemetry-collector#14115) and description metadata fields for components. Related to open-telemetry/opentelemetry-collector#14114 and open-telemetry/opentelemetry-collector#14400 Continuation from open-telemetry#45537 open-telemetry#45554 open-telemetry#45599 I did not include the skywalking extension because I am handling that in a separate PR due to it having a missing doc file --------- Co-authored-by: Christos Markou <chrismarkou92@gmail.com>
