Description

Fixing the following five errors in Presto doc builds that have crept in over time.

/Users/steveburnett/Documents/GitHub/presto/presto-docs/src/main/sphinx/connector/hive.rst:324: ERROR: Content block expected for the "note" directive; none found. [docutils]
/Users/steveburnett/Documents/GitHub/presto/presto-docs/src/main/sphinx/connector/hive.rst:325: WARNING: Explicit markup ends without a blank line; unexpected unindent. [docutils]

/Users/steveburnett/Documents/GitHub/presto/presto-docs/src/main/sphinx/admin/jmx-metrics.rst:189: WARNING: Bullet list ends without a blank line; unexpected unindent. [docutils]

Motivation and Context

Reducing doc build errors when possible improves the doc build time, and improves the ability to debug doc builds by eliminating fixable errors in the doc build.

Impact

Documentation.

Test Plan

Local doc builds.

Before:
build succeeded, 61 warnings.

After, the five warnings shown above are gone from the doc build output:
build succeeded, 56 warnings.

Reviewer's Guide

Fixes several Sphinx/reStructuredText formatting issues in Presto documentation to eliminate specific docutils warnings and one error during doc builds.

File-Level Changes

Change	Details	Files
Correct Sphinx heading markup for the native_aggregation_memory_compaction_reclaim_enabled session property to satisfy title underline length requirements.	Adjusted the underline length for the native_aggregation_memory_compaction_reclaim_enabled heading so it matches the heading text width. Ensured the heading level and surrounding blank lines conform to Sphinx/reStructuredText conventions.	presto-docs/src/main/sphinx/presto_cpp/properties-session.rst
Fix malformed note directive in Hive connector docs that caused a docutils error and follow-on warning.	Added or fixed the content block following a .. note:: directive so it is no longer empty. Inserted required blank line(s) after the note directive block to avoid explicit markup/unindent warnings. Aligned indentation of the note body with Sphinx expectations.	presto-docs/src/main/sphinx/connector/hive.rst
Resolve bullet list formatting issue in JMX metrics docs to prevent list termination warning.	Added a trailing blank line after a bullet list to indicate the end of the list to docutils. Adjusted indentation or spacing around the list so Sphinx no longer reports an unexpected unindent.	presto-docs/src/main/sphinx/admin/jmx-metrics.rst
