docs: update shared docs during releases

[zhongkechen]

Summary

• add a required post-publication step to update Java SDK versions in the shared docs repository
• list the current runtime and testing dependency locations
• include a repository-wide search that also catches OpenTelemetry plugin dependencies
• document prerelease handling and the shared docs validation commands

Testing

• codespell RELEASE.md
• git diff --check
• verified every listed shared-docs path exists
• verified the documented rg command finds all current Java SDK dependency snippets

Maven tests were not run because this changes release documentation only.

[P2] Search beyond Maven XML tags

Requiring an exact <artifactId> tag skips Gradle/Kotlin DSL, inline coordinates, and versioned plugin filenames, despite the checklist requiring every literal SDK version to be updated. Search for the artifact-name pattern itself so all dependency syntaxes are covered.

Suggested change

	'<artifactId>aws-durable-execution-sdk-java(-testing|-plugin-otel)?</artifactId>' \
	'aws-durable-execution-sdk-java(-testing|-plugin-otel)?' \

The new shared-doc release search can miss non-Maven dependency references, potentially leaving stale versions.

Claude AI review

This PR only adds a new "## 4. Update the shared documentation" section to RELEASE.md (44 additions, 0 deletions, no code changes). It documents a post-publication step to sync the Java SDK version into the separate aws-durable-execution-docs repository.

Review notes:

• The rg pattern '<artifactId>aws-durable-execution-sdk-java(-testing|-plugin-otel)?</artifactId>' correctly matches all three published artifact IDs (aws-durable-execution-sdk-java, aws-durable-execution-sdk-java-testing, aws-durable-execution-sdk-java-plugin-otel), verified against sdk/pom.xml, sdk-testing/pom.xml, and otel-plugin/pom.xml.
• Section numbering (## 4. following existing ## 1.–## 3.), terminology ("runtime SDK, testing library, OpenTelemetry plugin"), and the "without a leading v" phrasing are consistent with the rest of RELEASE.md.
• No code, tests, public API, checkpoint/replay, or concurrency logic is touched, so the SDK-focused review criteria (serialization, replay semantics, thread coordination, etc.) do not apply here. No tests are required for a docs-only change, consistent with CONTRIBUTING.md/AGENTS.md.

No code-level or correctness issues were found in this diff.

Residual risk: the new instructions reference file paths and tooling (docs/sdk-reference/..., mdformat, codespell, scripts/check_example_refs.py, zensical) that live in the separate aws-durable-execution-docs repository. None of these can be validated from within this repository, so their accuracy relies entirely on the PR author's manual verification described in the PR body; a future drift in that repo's structure or tooling would silently make these instructions stale.
