### Motivation
<!-- Explain here the context, and why you're making that change. What is
the problem you're trying to solve. -->
The test was written with the incorrect assumption that the compared strings
have a deterministic order. Since the original data was stored with
[HashMaps](https://docs.oracle.com/javase/8/docs/api/java/util/HashMap.html),
which makes no guarantees to the order of it's map, the resulting strings that
were compared could potentially have reordered contents. The ordering can
change due to different environments producing the contents in different orders
despite the logical contents being the same. Since the raw strings/trees were
compared "as-is", harmless re-ordering could flip the test from pass to fail
despite the data being semantically the same.
### Modifications
<!-- Describe the modifications you've done. -->
We no longer compare the raw strings "as-is", we instead convert the strings
into BsonDocuments which are [ordered](https://bsonspec.org/spec.html) to fix
the nondeterminism. This ensures the tests pass consistently, even in cases
where the original contents were in a different order due to the usage of
HashMaps.
In essence, these changes keep the spirit of the original tests while
eliminating failures caused solely by allowed (but previously unexpected)
reordering.

<!--
After opening this PR, the build in apache/pulsar will fail and instructions
will
be provided for opening a PR in the PR author's forked repository.
apache/pulsar pull requests should be first tested in your own fork since
the
apache/pulsar CI based on GitHub Actions has constrained resources and quota.
GitHub Actions provides separate quota for pull requests that are executed
in
a forked repository.
The tests will be run in the forked repository until all PR review comments
have
been handled, the tests pass and the PR is approved by a reviewer.
