feat(api-logs)!: change scopeAttributes to be of type LogAttributes

[AnubhavPurohit691]

Which problem is this PR solving?

LoggerOptions#scopeAttributes was typed as Attributes (from the trace API). Scope attributes are part of the logs API and should use the same value space as log attributes. Using LogAttributes (AnyValueMap) is correct because:

• Consistency: Scope attributes are associated with log telemetry; the logs API should use LogAttributes.
• Value space: LogAttributes allows nested objects, Uint8Array, null/undefined, etc.; trace Attributes only allows primitives and arrays of primitives.
• Stability: Changing this type later would be breaking for implementers; fixing it now avoids a future breaking change.

This PR updates the type to LogAttributes and adds tests plus a changelog entry.

Fixes #6350

Short description of the changes

• experimental/packages/api-logs/src/types/LoggerOptions.ts: Change scopeAttributes type from Attributes to LogAttributes; import from ./LogRecord instead of @opentelemetry/api.
• experimental/CHANGELOG.md: Add entry under Unreleased → Bug Fixes.
• Tests: In noop-logger-provider.test.ts, add tests that getLogger accepts scopeAttributes with primitive and full LogAttribute value types. In proxy-logger.test.ts, add test that options (including scopeAttributes) are passed through to the delegate.

Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• NoopLoggerProvider: getLogger('logger-name', undefined, { scopeAttributes: { ... } }) with (1) primitive values and (2) full LogAttribute value types (string, number, boolean, array, nested object, Uint8Array, null). Assert returned logger is a NoopLogger.
• ProxyLoggerProvider: getLogger('test', 'v0', { schemaUrl, scopeAttributes }) with scopeAttributes containing primitives, nested object, and Uint8Array. Assert delegate getLogger is called with the same options and scopeAttributes is forwarded.

Run: cd experimental/packages/api-logs && npm test — all 18 tests pass, including the new scopeAttributes tests.

• Test A (NoopLoggerProvider scopeAttributes acceptance)
• Test B (ProxyLoggerProvider scopeAttributes forwarded to delegate)

Checklist:

• Followed the style guidelines of this project
• Unit tests have been added

this is not a bugfix for sure, but a breaking change feature.

please move this up to breaking changes :)

This is pending a decision and the ticket is not yet ready to be worked on, see #6350.
Note that if we decide to do this, the PR also needs tests in sdk-logs.
