Add visual indicator for synthetic otel attributes

[DCchoudhury15]

Closes jaegertracing/jaeger#7696

This PR adds a visual indicator for attributes starting with otel. in the Trace Detail view. These attributes are synthetic artifacts of OTLP translation and are not directly searchable in storage backends like Elasticsearch.

Changes

• Detects keys starting with otel. in KeyValuesTable.tsx.
• Applies italic styling and specific color to differentiate them.
• Adds an Info icon (ⓘ) with a tooltip explaining that the attribute is synthetic.
