docs: updates dd & otel docs for plugin filtering

[roroghost17]

Summary

Documents the plugin_span_filter configuration option for the Datadog connector, and corrects the UI navigation path for the OTEL connector's plugin span filtering instructions.

Changes

• Added a new Plugin Span Filtering section to the Datadog connector docs, covering exclude/include filter modes, config.json usage, UI configuration, built-in plugin names, child span re-parenting behavior, and a note on per-connector filter independence and config versioning precedence.
• Updated the OTEL connector docs to correct the UI navigation path from the generic "Plugins page" to the specific Observability page → Open Telemetry connector flow, matching the Datadog connector's updated instructions.

Summary by CodeRabbit

• Documentation
  • Added a Plugin Span Filtering guide for Datadog APM explaining how to include/exclude plugin execution spans, supported filter modes (include/exclude), built-in plugin names, example configuration, and how filtering re-parents child spans in traces.
  • Clarified OpenTelemetry connector docs to use the Observability page for plugin tracing and that connector config can override UI-saved filters by version.

"🐰 I hopped through docs with a curious nose,
Added filters where the plugin-span goes.
Datadog learns which spans to keep or shed,
OTEL points the way—now rest your head.
A little hop, a clearer trace, off to bed! ✨"

Confidence Score: 5/5

Documentation-only change with no runtime impact; all documented fields and values are accurate against the config schema and codebase.

Both files touch only Mintlify documentation. The new plugin_span_filter example, filter modes, built-in plugin names, and version field placement were all cross-checked against transports/config.schema.json and the plugins directory — everything matches. The OTEL path correction is a straightforward factual fix.

No files require special attention.
