feat(attributes): Add sentry.pageload.span_id attribute

[Lms24]

Description

Already sent by the browser SDK on v1 and v2 web vital spans. Also helpful for web vitals as metrics

PR Checklist

• I have run yarn test and verified that the tests pass.
• I have run yarn generate to generate and format code and docs.

If an attribute was added:

• The attribute is in a namespace (e.g. nextjs.function_id, not function_id)
• I have used the correct value for apply_scrubbing (i.e. manual or auto. Use never only for values that should never be scrubbed such as IDs)

If an attribute was deprecated:

• I've followed the policies described in CONTRIBUTING.md

Span ID uses manual scrubbing

Medium Severity

sentry.pageload.span_id is defined with apply_scrubbing manual, but it holds a pageload span identifier used to link web vital spans and metrics. Other Sentry span ID attributes (sentry.segment.id, sentry.replay_id, sentry.trace.parent_span_id) use never, and project guidance treats opaque IDs that way so scrubbing does not break correlation.
