spanner IT fails for `deleteAllById_doesNothingOnEmptyIds` test with error from Spanner:
`INVALID_ARGUMENT: Failed to initialize transaction due to invalid mutation key.`

**Trigger of this behavior change:**
spanner activated multiplexed sessions by default in [googleapis/java-spanner#3996](googleapis/java-spanner#3996), which triggers this error. 
When issuing a write() with a Mutation that has an empty KeySet produces an exception in Multiplexed clients (see [pr](googleapis/java-spanner#4023)), but does a no-op in non-multiplexed ones. Unlike Regular session, multiplex session needs a valid mutation to generate a precommit token.

The table of contents for the [documentation of Spring Cloud GCP
7.1.0](https://googlecloudplatform.github.io/spring-cloud-gcp/7.1.0/reference/html/index.html)
shows '22. Global Secrets' and '23. Regional Secrets' as sibling
sections after '21. Secret Manager', but I believe they should be
subsections of 'Secret Manager', and they are also part of the
`secretmanager.adoc` file.

This pull request changes these sections to be subsections of Secret
Manager.


Fixes #4072

Fixes
#3610

Modifies the ghpages.sh script to update the root documentation
directory (e.g., /reference/html/) in the gh-pages branch *only*
when a versioned release is being processed (using the -v flag).

This is achieved by adding calls to copy_docs_for_branch within the
copy_docs_for_provided_version function to target the root
destination folder, in addition to the version-specific folder.

This ensures the version-less URL always points to the latest
officially released documentation.
